Power and control terminal boards.
Electric duct heater scr control.
An electronic step controller provides electronic sequencing control of an electric duct heater up to 12 steps.
Scr power controllers are designed for an accurate and cost effective way to modulate electric heat.
Phase angle fired zero voltage switched and on off control.
Since the scr is solid state it.
Standalone coils supplied as duct heaters are certified in compliance with ul 1996.
Our heaters and controls range from standard duct heaters to the most sophisticated custom designed comprehensive systems.
Capacity and stages are dependent on voltage phase and heater dimensions.
When interruption of power occurs all stages cycle off.
Fuses to protect each circuit in any heater drawing more than 48 amps.
Heavy gage g60 construction with hinged access cover.
Electric reheat coils are an available accessory for use with price single duct and fan powered terminal units.
Automatic reset thermal safety switch for primary over temperature protection.
These controls proportionally turn on a percentage of each power line half cycle.
Price electric coils are factory mounted etl listed to meet electrical safety standards and comply with dual designation csa 236 ul 1995.
The scr control can deliver electrical power to heaters in several ways.
A silicon controlled rectifier scr is a solid state switching device which can provide fast infinitely variable proportional control of electric power.
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.
Their applications vary from a partial or auxiliary nature to being the major or principal heat source in a building.
Indeeco s attention to detail and rigorous testing give worldwide customers premium products that they receive quickly and at a fair price.
Manual reset thermal safety switch for secondary over temperature protection.
Scr power control in depth.
This duct heater features.
Scr pictured solid state relays are used to provide continuous modulation.
Upon restoration of power the step sequence resumes.
Not only does this give maximum control of your heat process but it can extend heater life many times over other control methods.
Useful for electric reheat and supplemental electric duct heaters.
