Remarks:
Double output units tted with H-15 connectors have the
output pins of the second output, pins 4/6 and 8/10, inter-
nally paralleled.
It is recommended that pins 4/6 and 8/10 be directly paral-
leled at the female connector as well to reduce the voltage
drop across the connector.
Please note:
Uo2 varies depending upon its own load and
the load on output 1.
1 A ceramic multilayer capacitor connected across the output
lines reduces ripple and spikes.
2 Shortest possible wiring for series connection at the female con-
nector
