The ULC/3P phase angle power controllers are ideal for control of single-phase 230Vac applications. They have on/off and 3 selectable positions and are 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 also easy to installed, only a fixing hole and locking nut to hold it in place. A scale plate and 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.

 

New from Under Control Instruments, high-specification 8820 series digital controllers are supplied as standard with 20A relay outputs and two NTC sensors. They are suitable for many applications requiring on/off temperature control of heating or cooling systems.

These digital thermostats can also be used as replacements for normal capillary thermostats as the prices are now comparable.

The UVR/S is a Phase Angle Power Regulator, designed for single-phase 230VAC. The load current can be upto a maximum of 15A.

The module gives full adjustment of the output voltage from on/off 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.

To prolong the life of the unit we also recommend the use of our heat-sink paste for applications of 5A and above.

UVR/S AC Power Regulator (Dimmer)
Solid State Relays

We offer a range of single and three phase solid state relays available for chassis or Din mounting. They are supplied with a protection cover and LED indicator.

Please call for more details.

The UVR/S power regulators (dimmers) switch is also supplied in its own enclosure  for wall mounting application. This also acts as its own heat sink.  

Measures 65 W x 120 L x 40mm D

Temperature Sensors

Thermocouples,  PT100 and thermistors are used where the measurement of a process temperature is required. In general PT100 and PT1000 are more accurate over larger temperature spans and thermocouples are generally more cost effective.

We offer many sizes from stock, if not stock we can supply them in days if required.

 

Common styles

The most common thermocouples are K and J. Common PT100 probes both 2 and 3 wire designs.

Features and Applications

 

4-wire PyroCouple sensors provide a voltage or thermocouple output (J, K or T) representing target temperature, plus a 4 to 20 mA output proportional to the sensor temperature. Typical applications might include:
