Hoyles Power Supply

24 volt 1A dc general use switched mode power supply. The unit is capable charging Lead Acid batteries (NOT supplied). Housed in a steel case, intended for internal use only. All units have protection from AC input surges and transients, under and over AC power, over-heating and over-current, battery-reverse connection and over-current battery charge, substantially removing the need for engineer visits to rectify such problems.

Virtually no heat produced means they can be installed almost anywhere without the need for noisy cooling fans
Unique battery charging feature reduces strain on batteries, thus prolonging their life
Self-resetting electronic fuses auto-reset after problem goes away, helping reduce engineer call outs
Anti-'spike' filtering protects access system from downtime due to blown fuses caused by electric/magnetic door releases
'Green' technology will save at least 131KWh of electricity p.a. for each 1A unit
