Since the scr is solid state it.
Electric duct heater scr control.
These controls proportionally turn on a percentage of each power line half cycle.
Indeeco s attention to detail and rigorous testing give worldwide customers premium products that they receive quickly and at a fair price.
Heavy gage g60 construction with hinged access cover.
Useful for electric reheat and supplemental electric duct heaters.
Their applications vary from a partial or auxiliary nature to being the major or principal heat source in a building.
The scr control can deliver electrical power to heaters in several ways.
This gives smooth infinitely variable application of power to the heaters.
Electric reheat coils are an available accessory for use with price single duct and fan powered terminal units.
Thermolec electric duct heaters are designed for use in all forced air commercial and industrial hvac systems.
A transformer with any overcurrent protection required by ul or the nec to supply the internal control circuit of 120 volts per heater with a step controller for vernier control and 24 volts for all other heaters with scr control.
Manual reset thermal safety switch for secondary over temperature protection.
Viconics r820 scr power controller has been designed for safe and reliable control of electric heat loads.
Power and control terminal boards.
Scr power control in depth.
Upon restoration of power the step sequence resumes.
Our heaters and controls range from standard duct heaters to the most sophisticated custom designed comprehensive systems.
Price electric coils are factory mounted etl listed to meet electrical safety standards and comply with dual designation csa 236 ul 1995.
Phase angle fired zero voltage switched and on off control.
Automatic reset thermal safety switch for primary over temperature protection.
Scr pictured solid state relays are used to provide continuous modulation.
This duct heater features.
Fuses to protect each circuit in any heater drawing more than 48 amps.
Scr power controllers are designed for an accurate and cost effective way to modulate electric heat.
Capacity and stages are dependent on voltage phase and heater dimensions.
An electronic step controller provides electronic sequencing control of an electric duct heater up to 12 steps.
Not only does this give maximum control of your heat process but it can extend heater life many times over other control methods.
