Power-io solid state relays and i/o modules

New solid state relays, solid state contactors, or din rail io modules.


solid state relays and heatsink

New heat sink, matches the width of the SSR

The new Power-io heat sink is 1.77 inches wide, which matches the width of our solid state relays. This pemits higher density installations when the amperage requirements are low to medium. Larger heat sinks are available if the amperage requirements are higher or if the cabinet temperatures are warmer. The Power-io HEATSK-DIN-2.0 can be din rail mounted or it can be attached with screws to your electrical enclosure.


thermal compound, thermal grease

How to apply thermal compound (thermal grease)

All solid state relays (or computer CPUs or many other electrical devices) generate heat when they are working. A proper application of thermal compound helps to ensure the best thermal transfer from the device to a heat sink. In this example, we are showing the application of thermal compound on the Power-io C Family product. The Power-io can be switching up to 100 amps per channel, which is 200 amps total. This thermal rise can be effectively transferred to the Power-io heat sink while occupying a tiny footprint of less than 22 square inches of cabinet sub-plate.


 analog 4 to 20 input contactor

New 4-20mA input SSR, including high speed performance

The HMA product lines accepts an industry standard 4-20mA analog signal, or a potentiometer, and converts that control request into high speed on/off/on/off pulses for heater control. The switching is electrically-clean zero-crossing. The internal microprocessor calulates the minimum number of half sine waves, starting at 3 half sine waves, and adds additional ON or OFF half sine waves to meet the target. For longer heater life or high speed IR loads, sealing bars, IR heaters for extrusion preforms, or extruder die zones; the HMA can provide up to 20-40 precise on/off heat cycles per second. The HMA product is made in the USA.

Zener Diode

How to: use a voltage divider, or diode, to change the control input

By installing a voltage divider, or a zener diode, in front of the Power-io's control input, you can change the input range. For example, if you have a 48 VDC control signal from a solar application, using a voltage divider or diode, we can reduce that so that it is an acceptable control input signal.

UPC heat sink

New -- Ultra Power Cooler™ Heat Sink

Solid state relays are semiconductor devices that generate heat in proportion to the quantity of amps being switched. Heat sinks capture that thermal rise and dissipate it. Heat sinks are rated by a ºC/W number that represents: "for every watt of heat generated, the solid state relay will increase by xºC". For example: if you put 30 watts of heat on a 3ºC/W heat sink, the solid state relay's internal SCR dies will rise 90ºC (194ºF) above the ambient temperature. The new, 80 mm (3.15 inches) wide Ultra Power Cooler heat sink provides a 0.2ºC/W rating that makes it ideal for high amperage solid state relays, high ambient temperature areas, or high density installations. Power-io manufactures a variety of heat sinks for industrial, military, or commercial installations. February 16, 2005


90 amp solid state relay

New -- 90 and 125 amp solid state relays

The popular H family of solid state relays has been expanded with two new high current models offering 90 and 125 amp AC switching outputs.

When used at lower amperage switching, such as 20-75 amps, these new models offer cooler performance while ensuring a higher margin of safety against amperage inrush problems. Both models have the Maximum Surge Survival™ circuit for outstanding performance and long life in industrial, laboratory, military, or appliance installations. The models use a precision zero crossing method for the lowest possible EMI (noise) without additional filters or other add-ons. Low noise is an international CE requirement as well as a requirement for medical, test equipment, or other precision applications. January 9, 2005
