Fig. 21e
LS 5000 with H15 connector. R-input for output voltage
control. Wiring of main and second output for two output
voltages Uo1 and Uo2: 12 V/12 V or 15 V/15 V or
24 V/24 V, the outputs are galvanically isolated.
1 A ceramic multilayer capacitor connected across the load re-
duces ripple and spikes.
2 Shortest possible wiring for series connection at the female con-
nector
Remarks:
Double output units fitted with H15 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.
