max. 400 V AC or 300 V DC

- Protection of power feed (must be ordered):
- Power pack A:
ABB Stotz m.c.b.: S 282 UC-K, 1.6 A
- Power pack B:
ABB Stotz m.c.b.: S 282 UC-K, 1.0 A
- Power consumption on the input side during a charging
process: ca. 100 W
- Power consumption in normal position: P < 10 W
- Charging times of the capacitor (example for DC voltage):
a) Initial charging on commissioning:
- Breakers to 25 kA: max. 10s
- Breakers from 31.5 kA: max. 15s.
depending on the supply voltage.
In this time, the capacitor(s) is/are charged to 80 V, and
an ON-OFF operating cycle is already possible at 72 V.
(The ”READY” lamp indicates readiness for switching.
A flashing “READY” lamp signals recharging of the ca-
pacitor. Switching readiness is enabled during that time).
b) Recharging after a switching operation to a charge of
80 V: max. 5s.

In general, with AC signals which are connected via long lines, it should be checked
whether the installed base load of 300 kΩ is sufficient (mutual capacitive coupling!)
to ensure a reliably low interference level. Otherwise, an appropriately dimensioned
resistor or capacitor is to be connected in parallel at the input terminals.
