HACA 5-20PC Series

HACA5-20PC Series

HACA5-20PC Series AC Ammeters are designed to scale and digitally display the output of standard, 5A-output current transformers (50:5A, 500:5A, 1000:5A, etc.). Simply pass the secondary/output wires of the “primary” CT through the HACA5-20PC’s on-board CT, apply power to the meter, and you’re instantly measuring ac currents over one of 14 ranges from 0-50A (with 100mA resolution) to 0-2000A (with 1A resolution). Because they accept outputs from previously installed high-current CT’s, HACA5-20PC’s can instantly bring modern digital precision to older ac ammeters. The functionally complete HACA5-20PC ammeters incorporate scaling/interface circuitry to mate the on-board CT to a precision (3½ digit) A/D converter. The A/D’s output directly drives the meters’ large (0.37″/9.4mm digit height), easy-to-read, LED displays. All models employ auto-zero circuits, precision bandgap references, and super stable metal-film resistors for unsurpassed accuracy (±0.15%FS) and stability. HACA5-20PC meters are either ac (120/220Vac @ 50/60Hz) or dc (+5-40V) powered. AC models can be powered by the same ac supply whose current they are monitoring. All HACA5-20PCs provide 2000Vdc isolation between the measured ac current and their power supply, and all models are UL/CSA recognized. Each meter is housed in a subminiature, 1.38″ x 0.88″, epoxy-encapsulated package whose behind-the-panel installation depth is 2 inches. Display color options include standard red, high-intensity red, and standard green. Each meter is supplied with a plastic bezel assembly with sealing gaskets (MPS DMS-BZL4-C).

HACA-20RM Series

HACA-20RM Series

Hoyt’s new HACA-20RM Series are the world’s first digital ac-ammeters to incorporate a built-in current transformer (CT) to directly measure the true-rms value of complex, non-sinusoidal ac currents from 2 to 50A – no bulky and expensive 5A “donut” CTs are required! Operation and setup is straightforward: simply pass the load-carrying wire through the on-board CT, apply power, and the ammeter is fully operational. Five input ranges measure 0-0.2 amps (0.1mA resolution), 0-2 amps (0.001A resolution), 0-20 amps (0.01A resolution), 0-30 amps (0.1A resolution) or 0-50 amps (0.1A resolution). The 50A model features an oversized split-core current transformer that easily accommodates wires sizes up to 4 AWG (21.2mm2). Two power supply options are available: 85-140V (47-63Hz), and 170-264V (47-63Hz). All models are totally self-contained; no external components are required. Power consumption from a nominal 120V or 220V ac supply is less than 50mA. And, precision autozeroing circuitry, super-stable components, and an rms-to-dc converter circuit combine to achieve excellent performance when measuring the complex, non-sinusoidal, ac currents found in today’s computer/telecom equipment. HACA-20RM Series ammeters feature full-size, 0.37″ (9.4mm) high, 3½ digit, bright red LED-displays and a built-in bezel/filter assembly that features metal fasteners. They are panel-cutout compatible with Hoyt’s HDMS-20 Series of ac voltage and frequency monitors, making HACA-20RM ammeters perfect replacements for older, less reliable, analog panel meters in today’s sophisticated IT instrumentation.

DMS-30PC

DMS-30PC Series

The DMS-30PC Series is a broad line of self-contained, fully operational, 3½ digit voltmeters with large, easy-to-read LED displays. The 0.56″(14.2mm) high LED’s are available in a wide variety of colors including red, orange, amber, yellow, green, aqua, blue-green, and super-blue. A high-intensity version of the red display is optional, as are low-power versions of the red, orange, and green displays. The small size (2.17″ x 0.92″ x 0.56″) of DMS-30PC meters is achieved by integrating their display, display drivers, reference circuit, and A/D converter into in a single, epoxy, encapsulated assembly. The device’s 12-pin, component-like, DIP package is both vibration and moisture proof. Each package incorporates a built-in color filter and bezel and is easily mounted in either panels or pc cards. These meters are available in four differential input voltage ranges (±200mV, ±2V, ±20V and ±200V). Input impedance is 1,000 mega ohms for the ±200mV and ±2V inputs and 1 mega ohm for the ±20V and ±200V inputs. CMRR for all devices is 86dB, and inputs are over voltage protected to ±250V. Each meter incorporates an extremely stable, double-regulated reference and is fully calibrated prior to potting. We guarantee outstanding initial accuracy (±1 count) and excellent stability (±0.15 counts/°C). All models operate from a single +5V supply, and the low-power models draw as little as 10mA (50mW total power). A DISPLAY TEST function is standard on each device. For popular applications (4-to-20mA, rms-to-dc conversion, ac line power, J and K thermocouples, etc.), the DMS-30PC Series includes a complete line of optional “plug-on” application boards that conveniently convert your meter into an application-specific instrument.

The large, 0.37″/9.4mm digits exhibit uniform intensity over the entire 4-20mA operating range. Additionally, the total maximum loop voltage drop is only 5V! Users no longer have to settle for difficult-to-read LCD displays in loop-powered applications. Both gain (span) and oset (zero) adjustments are performed with on-board, precision, 20-turn potentiometers. All decimal-point and range-change selections are made on a six position DIP switch featuring vibration-resistant, gold-plated contacts. Unlike competitive meters, there are no jumpers or solder gaps to open or close. Connections to the current loop are made via a reliable, two-position, screw-type terminal block. The DMS-20PC-4/20’s DIP switch and adjustment potentiometers accommodate hundreds of dierent input-current/output-reading combinations. This versatility practically eliminates the need to order more costly, long-lead-time, factory-customized “specials” in applications in which several dierent-range meters are required. An optional bezel assembly, featuring screw fasteners and a rubber seal, simplifies panel mounting and provides excellent resistance to environmental dust and moisture. All these outstanding features combine to make the DMS-20PC-4/20 Series the perfect meters for prototype and OEM 4-20mA current-loop instrumentation.

DMS-20PC 0/5 Series

DMS-20PC-0/5 Series

Hoyt’s DMS-20PC-0/5 Series are the world’s smallest, full-featured, 0-5V input process control monitors. Their large, easy-to-read, 0.37″/9.4mm LED displays are available in a choice of 4 LED color/intensity options: standard red, standard green, super-bright red, and low-power red. Two power supply input ranges are also available: the industry-standard +5V and a wide-range +5V to +40V (which typically draws 9mA at +24V). Gain (span) and oset (zero) adjustments are performed with on-board, precision, 20-turn potentiometers. All decimal-point and range-change selections are made on an 8-position, vibration-resistant, gold-plated DIP switch. Unlike competitive meters, there are no jumpers or solder gaps to open or close, and to further enhance reliability, the entire assembly utilizes 100% soldered connections. Both power-supply and input-signal connections are made via reliable screw-type terminal blocks. The DMS-20PC-0/5’s DIP switch and potentiometers accommodate hundreds of input voltage/ output-reading combinations. This practically eliminates the need for more costly, long-lead-time, factory “specials” in applications which use several dierent-range meters. A supplied bezel assembly––featuring metal fasteners and a rubber gasket––simplifies panel mounting and also provides excellent resistance to environmental dust and moisture.

DMS-20PC

3½ Digit, LED Display, Digital Panel Voltmeters combine a precision A/D converter; a factory-trimmed, highly stable, voltage reference; and a large (0.37″/9.4mm), easy-to-read LED display in a single package that is only slightly larger than the display itself. Displays are oered in either red, orange, amber, yellow, green or blue colors. High-intensity and low-power (35mW total) red LEDs are also optional. These low-cost meters are fully self-contained and fully functional. Their subminiature (1.38″ x 0.88″ x 0.48″), epoxy-encapsulated cases incorporate built-in color fi lters and bezels; are moisture and vibration proof; and function well in the harshest environments. Their 12-pin, dual-in-line confi guration oers component-like, plug-in convenience and maximum versatility. Operating temperature range is 0 to +60°C. The meters come with one of four, dierential, input voltage ranges: ±200mV, ±2V ±20V or ±200V. Input impedance is a minimum 800k. CMRR is typically 86dB (dc to 60Hz), and CMV is ±2V. Input overvoltage protection (on the non-inverting input) is ±250V. Devices are fully calibrated at the factory to an accuracy of ±1 count (±0.05% of full scale range) and never require calibration or adjustment. A DISPLAY ENABLE function permits the display to be disabled for “power-down” operation. All models have a DISPLAY TEST function. Standard red LED models oer an optional DISPLAY HOLD function. Small size, low cost and adjustment-free reliability make the DMS-20PC Series the best choice for all your 3½ digit, LED, DPM applications.
