230 V AC emergency power changeover for lighting
Article number PR161
In normal operation the lighting is fed from the main circuit. If that fails, for example due to a short circuit or a faulty generator, the PR161 automatically switches the lighting to the emergency circuit. The coil of the changeover relay has its own terminals, so an external monitor, for example of mains voltage and frequency, can also control the changeover. The contacts switch up to 8 A resistive or 3 A with an AC-15 type load.
- Supply 230 V AC
- Output lamp circuit 230 V AC, 8 A resistive or 3 A AC-15 load max.

Specifications
| Supply | 230 V AC |
|---|---|
| Output | Lamp circuit 230 V AC, 8 A resistive or 3 A AC-15 load max. |
| Dimensions | 45 x 83 mm with DIN rail enclosure, 42.5 x 72 mm without |
Connections
| Terminal | Function |
|---|---|
| Terminal Hoofd N | Neutral of the main circuit |
| Terminal Hoofd L | Live of the main circuit |
| Terminal Nood N | Neutral of the emergency circuit |
| Terminal Nood L | Live of the emergency circuit |
| Terminal Lamp N | Neutral of the lighting |
| Terminal Lamp L | Live of the lighting |
| Terminal Relay N | Neutral of the relay coil; connect to the neutral of the main circuit for automatic changeover |
| Terminal Relay L | Live of the relay coil; connect to the live of the main circuit for automatic changeover |
Setup
- Connect the main circuit to Hoofd N and Hoofd L, the emergency circuit to Nood N and Nood L and the lighting to Lamp N and Lamp L.
- For automatic changeover, connect Relay N to the neutral and Relay L to the live of the main circuit.
Application
- Automatically switching lighting in buildings, installations and on board to the emergency circuit when the main circuit fails
- Letting an external mains voltage and frequency monitor control the changeover
Emergency power and emergency lighting
These modules switch automatically to an emergency supply or emergency circuit when the main supply fails. The PR149 and PR161 use relay logic at 230 V AC, without digital circuitry; for these two another operating voltage, such as 120 V AC or 24 V DC, is available on request. The PR150 switches over a 24 V DC supply, is fully analogue, without microcontroller or software, and has an alarm contact.
PR149: the emergency lighting switches on as soon as the 230 V AC mains fails; in normal operation the lighting is controlled with a wall switch. PR161: when the main circuit fails, the lighting is switched to the emergency circuit; the changeover can also be controlled externally. PR150: changeover from main to emergency supply at 24 V DC, up to 8 A, with alarm contact.
