Note 1. Output ripple and noise to be measured with a 4.7uF +0.1 uF film or ceramic capacitor measured at points A as shown below.
Note 2. Output voltage to be measured at output terminals, Points B as shown below.
Note 3. OVS-5*-U has a dual rating of 3.2V and 5V. The unit is shipped from the factory set to 5V.
To obtain 3.2V, the unit must be modified according to the instructions.
Note 4. OVS-24*-U has a dual rating of 24V and 28V. The unit is shipped from the factory set to 24V.
To obtain 28V, customer must readjust the output voltage potentiometer.

D. Environmental
(1) Operating Temperature
MODELS –E, F & G:
0 to +40 deg. C with cover, 0 to +50 deg. C without cover*
In either case, the temperature at the center portion on the side of the
chassis should be +60 deg. C MAX.
For operation above +40 with cover (+50 deg. C without cover) derate
linearly to 50% load at +55 deg. C with cover (+65 deg. C without cover).
In either case, the temperature at the center portion on the side of the chassis
should be +70 deg. C MAX.
* Ambient temperature to be measured at 1” above the main transformer.
MODELS –H & J:
0 to +40 deg. C with cover, 0 to +50 deg. C without cover*
In either case, the temperature at the center portion on the side of the
chassis should be +60 deg. C MAX.
For operation above +40 deg. C without cover (+50 deg. C with cover)
derate linearly to 50% load at +55 deg. C without cover (+65 deg. C with cover).
In either case, the temperature at the center portion on the side of the chassis
should be +70 deg. C MAX.
