UVR/S  best choice

Our UVR/S Variable Phase Angle Power Regulator is designed for single-phase 230VAC. The load current has a maximum capacity of 17A. The module gives full adjustment of the output voltage from 0 to 98% of the load (scale plate included).

An in-house large triac enabled the unit to handle high inrush currents. Easy front panel mounting via a single hole and locknut arrangement.

These types of power controllers are used where simplicity of control is required. They operate on the same principle as a light dimmer by slicing the voltage wave smaller and smaller to reduce the power output.

They are used in industries such as commercial catering equipment manufacturers, packaging and plastics industries where the effect of on/off control is undesirable such as with the use of infrared heat lamps and quartz heaters.

They have a maximum working capacity of 17A which equates to 4000w with the correct heat sink and heat-sink paste applied.



The non-switched version is the UVR  suitable for control through the full percentage range.

(3 position selector)

The ULC/3P variable phase angle power controllers are ideal for control of single-phase 230Vac applications, some are as below. They have on/off and 3 selectable positions and also fitted with a RFI filter to comply with EMC regulations class A. The large triac enables the unit to handle high inrush current with ample safety margins on industrial installations. They are easy to installed, only a fixing hole and locking nut to hold it in place. A scale plate a turning knob supplied in the pack. To prolong the life of the unit we also recommend the use of our heat-sink paste for applications of 5A and above.
