Description
The power supply is factory preset at the customer specified output voltage between 22 and 28V DC (usually 27.6V DC).
Mains input is via a 3-pin plug and flex; output terminals for + and – connections are provided outside the case. A battery trickle terminal is also provided, although the main output can be directly connected to a battery.
Installation
The power supply should be installed in a well ventilated area and not enclosed where excessive heat build up can occur. Do not install or mount above any hot air discharge/air-conditioner/radiator or similar equipment. Mounting outside or in a wet/damp environment is also not recommended.
Batteries
Sealed and open lead acid batteries can be charged. Please specify nominal output float voltage and size of battery when ordering.
