Ancillaries - Power Supplies
PSS manufacture a range of Power Supplies/Chargers at different ratings and with various enclosure options. All PSUs are 24V nominal unless stated otherwise and rated at continuous current. They are designed to operate from 220-240 v.a.c. 50Hz.
Where the PSU has fault-monitoring, the Mains Fault relay and the Battery Fault relay will be energised and will de-energise when in fault. A change-over contact is provided in each case. The battery monitoring will show fault when the battery is disconnected or when the battery voltage is 20% below normal.
Enclosures are finished painted in semi gloss RAL 9002 grey-white powder coat, optionally they may be supplied painted black.
