The SMPS12-10 is a fully regulated adjustable voltage power supply which incorporates a unity power factor correction capability, drawing sinusoidal input current from the mains supply with a power factor greater than 0.96 under most load situations. This feature optimises input power usage making the power supply suitable for alternative energy projects or other applications where efficiency is critical. The output voltage is normally preset at the factory. Please consult Customer Services for your voltage requirements when ordering.

| Note: | There are no user serviceable parts inside the power supply and it is extremely dangerous to remove the cover while the unit is switched on, as live circuitry inside may be exposed. |

The power supply is factory preset at the customer specified output voltage between 11 and 14V DC (usually 13.8V 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.
|
|
Electronic limit can be disabled for large peak loads > 10A (e.g radio transmitters, motors...etc).
|
|
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.
