4 Environmental

The following subsections define recommended environmental specifications and test parameters, based on the typical conditions a TFX12V power supply unit may be subjected to during operation or shipment.

4.1 Temperature

Operating ambient: +10 °C to +50 °C (At full load, with a maximum temperature rate of change of 5 °C/10 minutes, but no more than 10 °C/hr.)

Non-operating ambient: -40 °C to +70 °C (Maximum temperature rate of change of 20 °C/hr.)

4.2 Thermal Shock (Shipping)

Non-operating: -40 °C to +70 °C

15 °C/min ≤ Dt/dt ≤ 30 °C/min. Tested for 50 cycles; Duration of exposure to temperature extremes for each half cycle shall be 30 minutes.

4.3 Relative Humidity

Operating: To 85% relative humidity (non-condensing)

Non-operating: To 95% relative humidity (non-condensing)

Note: 95% RH is achieved with a dry bulb temperature of 55 °C and a wet bulb temperature of 54 °C.

4.4 Altitude Requirement

Operating: To 10,000 ft

Non-operating: To 50,000 ft

4.5 Mechanical Shock

Non-operating: 50 g, trapezoidal input; velocity change ≥ 170 in/s

Three drops on each of six faces are applied to each sample.
