The solid state voltage regulator (SSVR) is for manually regulating the AC power. It works in the same way as a dial on an electric stove, or a dimmer for ceiling light. The main difference for the SSVR is that its power handling capability is much larger than a dimmer. A dimmer normally is limited to 5 A, or 600 W at 120 VAC. This SSVR can handle up 25 A. For 120 VAC, that translates to 3000 W, or 6000 W for 240 VAC. The SSVR kit contains a SSVR, a rheostat, and a dial.
Similar to solid state relay (SSR), SSVR also generates heat when current passes through it. Each ampere of current produces about 1.5 W of heat. User needs to mount it to a heat conducting metal surface, or use our SSR heat sink with proper current rating.
The resistance of rheostat required depends on the voltage and frequency of the power to be regulated. When ordering, buyer needs to select the proper value of voltage and frequency for the rheostat.
The dial plate is for reference position of the knob only. It does not represent the percentage of the output because the power output is not linear to the dial position. The middle section is more sensitive because of the Sine Wave of the AC power. The rheostat will carry the same voltage it regulates. Wiring should be insulated from contacting metal chassis.
The SSVR is ideal for resistance load application like heating element and some simple motor application. A lot of AC motor speed regulator applications require torque control, but we do not recommend the use of this product for it. Buyer will purchase at buyer's own risk and warranty is not covered.
Note: This SSVR should to be mounted on a heat sink to dissipate heat. Thermal grease (SI-07) or Silicone Thermal Pad (SI-PAD) should be applied between the SSVR and heat sink to help transfer heat. For more information, please see this link.
Typical Wiring
Output voltage increases when dial is turned clockwise.
(For decreasing output voltage, please use the pin 1 and pin 2 of the rheostat.)

*: The voltage mark on the SSVR block is 480V AC. It means the maximum voltage that can be applied on this SSVR block is 480V AC. You can still use this block under 120V or 240V without any issues. The voltage & frequency option is for the rheostat options. See table above for details.
