Phase Power Regulator PR1500i |
|
Purpose:
Phase power regulator PR1500i allows to control power in load from 0 to 97 % of maximum value.
Steel basis intended for strengthening to radiator is electrically isolated from all circuits. Smooth monotonous regulation on small conductance angles down to full cut-off is ensured.
PR1500i makes it possible to regulate:
- rotation speed of AC collector drives (in electric tools, vacuum cleaners, electromixers, kitchen combines, etc.);
- brightness of lighting incandescent lamps;
- power in electroheating equipment (heating system for living rooms, farm hothouses, electric soldering irons, etc.).

Recommendations for Application
- Do not allow to overflow the upper limit of operating temperature of case. It is recommended to mount steel basis of PR1500i on a heat-rejecting radiator. It is necessary to put heat-conducting ink between the mounting basis of the regulator and the radiator.
- It is recommended to connect RC-circuit between anode and cathode of the regulator in the case of working on inductive load impedance (see fig.2).
- Working of the regulator on capacitive load is not supposed.
- Recommended value of the variable resistor R1 is 1,0... 1,5 MOhm, dissipated power is 0,25V.
It is possible to obtain the lower limit of regulation range a min=0 with value R1 = 1,5 MOhm.
Decreasing of radiohandicapes level is ensured by using special filter (see fig.2).
Protection against electric shock should be ensured by construction of household device in which PR1500i is applied.
