Van Remmen 312430 Control unit 50W for V110, V120 and V130

The Van Remmen 312430 is a genuine 50W control unit for the V110, V120 and V130 UV disinfection systems, supplying and regulating the power your UV lamp needs to disinfect effectively. WrekinWater supplies this as a direct replacement for the original unit fitted to your system. It's the electrical heart of the unit, sitting outside the water path but essential to keeping the lamp running correctly.

Signs this needs replacing

• The UV system won't power on at all.
• The lamp fails to strike or stays dark even with a lamp you know is good.
• No indicator light or display activity from the control unit.
• A fuse blows repeatedly as soon as the unit is switched on.

The control unit supplies and regulates the electrical current that drives the 50W UV lamp inside your V110, V120 or V130 system, and on most models also carries the on/off switching and any status indication. If it fails, the lamp can't strike or run at the correct output, and water can pass through the reactor without being properly disinfected even though everything looks connected. Because it sits in the mains wiring, a faulted unit is a safety issue as well as a performance one.

How to replace it

1. Switch off and unplug the UV control unit from the mains supply before starting.
2. Note exactly how the lamp lead and any sensor or alarm cables connect to the old unit.
3. Disconnect the leads and remove the old control unit from its mounting.
4. Fit the new 312430 unit in the same position and reconnect each lead exactly as it was.
5. Restore the mains supply and check the lamp strikes and any indicator lights work correctly.
6. If your wiring isn't a straightforward plug-in match, or you're unsure working with mains electrics, ask a qualified electrician or water treatment engineer to fit it.
