- Input current in stationary conditions and maximum load (1 KW)
- AC 230 Vac: 7.4 A rms (19.3 A peak).
- AC 115 Vac: 13.3 A rms (28.0 A peak).
- DC 130 Vdc: 10.1 A.
- Inrush current
- AC 230 Vac: the inrush current value for the first start up is 35 A for each Line Module.
- AC 115 Vac: the inrush current value for the first start up is 18 A for each Line Module.
- DC 130 Vdc: the peak current for the first start up is 13 A.
- Crest factor
- AC 230 Vac: the ratio between peak value and effective voltage input is 2.6.
- AC 115 Vac: the ratio between peak value and effective voltage input is 2.1.
- Switching from Line 1 to Line 2 and vice versa (with two line Modules inserted)
If one of the two power sources fails, switch over from one Line to the other is automatic and instantaneous.
- Under voltage Signal
The alarm relay commutes if line voltage is less than 75% of nominal value.
- Turn-on Time
The time lapse between the application of line voltage and the instant in which output is stabilized is at maximum
300 ms.

- Voltage
Each Power Module provides a voltage of 24.7 V ±10%, adjustable by rotating trimmer accessible on front panel
of 1550-PM Modules. Voltage can be read via test points situated on panel front (refers to the readout upstream
from the decoupling diode present at outlet of each Module).
- Ripple
Output ripple is 100 mVpp at nominal load (36 A).
- Current
- Nominal Current: each Power Module delivers 6 A nominal (the current can be read via test points situated on
panel front: 100 mV correspond to 1 A output).
- Current alarm: each Power Module delivers up to 7 A before signalling alarm via relay.
- Current overload: each Power Module can deliver up to 7.5 A before limiting voltage. At 20.5 V output, the cur-
rent is about 8 A.
- Shortcircuiting: in overload conditions the output voltage starts pulsing when below 9 V; if after such conditions a
nominal load is applied (36 A), output reaches 24 V with maximum delay of 1.3 seconds.
- Output terminals
- Output Module type 1550/TB-OUT: out with 16+16 2.5 mm2 terminal blocks, up to 4 Amperes each.
- Output Module type 1550/TB-OUT 4/20: out with 4+4 6 mm2 terminal blocks, up to 16 Amperes each.
- Output Module type 1550/TB-OUT 60:out with 1+1 terminal blocks, up to 60 Amperes each.
