|
| The SMPS12-20 is a fully regulated adjustable output voltage power supply. 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 the cover may contact live circuitry inside. |

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. Keep fan intake/output vents well clear of any material likely to block them.
