The power supply is factory preset at the customer specified output voltage.
Mains input is via a 3-pin plug and flex; output terminals for + and - connections are provided outside the case.
The power supply is not recommended for float charging batteries above 60AH capacity (at C/20 rate).
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. Keep fan intake/output vents well clear of any material likely to block them.
 The above power supply is not suitable for charging the battery.
