Output Load De-rating VS Surrounding Air Temperature

Output Load De-rating VS Input Voltage

Fig. 1 De-rating for Horizontal Mounting Orientation

< -25°C de-rate power by 4.0% / °C @ 90-132Vac

> 50°C de-rate power by 2.0% / °C

Note

1. Power supply components may degrade, or

be damaged, when the power supply is

continuously used outside the shaded region,

refer to the graph shown in Fig. 1 & Fig.2.

2. The PSU will be bouncing and start up

time will not exceed 5s when ambient

temperature at ‐30 °C

3. If the output capacity is not reduced when the

surrounding air temperature >50°C, the

device will run into Over Temperature

Protection. When activated, power supply will

latch off, until the surrounding air temperature

is lowered or the load is reduced as far as

necessary to keep the device in working

condition, and require removal/re-application

of input AC voltage in order to restart.

4. In order for the device to function in the

manner intended, it is also necessary to keep

a safety distance as recommended in the

safety instructions while the device is in

operation.

5. Depending on the surrounding air temperature

and output load delivered by the power

supply, the device can be very hot!
