Humidity: 5 to 95 % RH non-condensing
Vibration: 2.4G 5 TO 500 HZ Protections:

a. Over voltage protection
b. Over power protection
c. Short circuit protection

Cooling: Free air convection

Note:

1. Vibration test: Three orthogonal axes, random vibration, 10 minutes for each axis.

2. Maximum output power is 25W.

3. At least 20% of load is required to obtain stable regulation.

4. Ripple & noise test method is measured at output terminal across a 0.1uF ceramic cap & a 10uF

tantalum cap in parallel with a 20MHz bandwidth oscilloscope directly.
