Unregulated PSU with independent battery charge circuit, calculated to to run at 13.6v at full load. If full load is not drawn the voltage will be higher. Battery charging is initiated by mains fail, as is a set of clean changeover contacts, which are available for remote signalling. Boxed in 310 x 310 x 110mm mild steel enclosure.

An unregulated PSU with an independent battery charge circuit. Calculated to run at 26v at full load. If the full load is not drawn the output voltage will be higher. Battery backup is connected via a relay when the mains fails, there is also a set of clean changeover contacts which are available for remote signalling. Chassis only.
