TEST PROCEDURE
Figure 12. Test Procedure Schematic
AC Input
(85
−
265 Vac)
16 V Output
0 V
32 V Output
WARNING:
Be careful when manipulating the boards in operation, lethal voltages up to 600 V are present on the primary side. An isolation
transformer is also recommended for safer manipulations.
Necessary Equipment
•
1 current limited 230 Vrms AC source (current limited
to avoid board destruction in case of a defective part)
•
1 DC volt-meter able to measure up to 50 V DC
•
2 programmable electronic loads
Test Procedure
1. Apply 110 Vac on the Vin pins. Output pins are
left floating.
2. Measure the output voltage between pins +16 V et
GND and b32 V and GND with a
volt-meter on the 50 V range. The measurements
should be respectively 16 and 32 volts (
±
10%).
