The D1P series controls are proportional, infinitely variable power controller capable of delivering 1-98% of the applied line voltage to the directly connected electric heaters. This is accomplished by phase angle firing a TRIAC module. The D1P will not control heaters with high inrush current (tungsten lamps), transformers or motors.

Electrical Connections N/A Check the Avatar serial tag and verify the correct voltage/ ampere ratings and input control signal for your application. Wiring must be performed in accordance with any and all applicable local and national codes. Use a minimum wire size of 12 AWG for a 20 amp D1P and a minimum of 10 AWG for a 30 amp D1P. For best results keep control signal and power wires separated.
Operation N/A The D1P comes standard with a potentiometer, knob and 0-100% scale which is used to vary the voltage to electric heaters, similar to a light dimmer and light bulb. WARNING: The potentiometer is NOT ISOLATED; it is at line voltage potential. The D1P cannot create more voltage or current than what is supplied to it.
Warranty N/A All Avatar Instruments products carry a full three year, from date of purchase, parts and labor warranty against component failure and defects in workmanship. In the event your controller fails to perform properly, contact Avatar to obtain a return authorization number. Controllers sent to Avatar for warranty service that have no apparent defect will be treated as a standard repair and a $50.00 charge will be applied. Avatar will repair or replace any unit that failed due to defective parts or assembly. This warranty DOES NOT cover damage due to shipping, abuse, misapplication or operation beyond specified rating. Further more fuses and improperly fused SCR's/ TRIAC's are NOT COVERED by this warranty. Avatar is not responsible for any subsequent or other damage experienced in use of this device.
