PSD1220 & PSD1220-098
- SIL 3 Power Supply, 24Vdc, 20 A, Zone 2, DIN Rail Mounting G.M. International ISM0370-3
2
General Description:
The Power Supply types PSD1220 and PSD1220-098 are anodized aluminum unit.
The Power Supply provides 24Vdc, 20 A output. PSD1220 or PSD1220-098 unit can be paralleled, with load sharing circuits, which distribute current load equally to each power supply
to increase reliability and reduce internal power dissipation.
The Power Supply accepts AC power input sources with nominal voltage range 110 to 240 Vrms (
±
10%). Therefore lower limit is 100 Vrms and upper limit is 264 Vrms.
The PSD1220-098 unit has got the same AC, DC, Fault and Current Sharing connectors used in the PSD1210 power supply module, for easy model to model replacement.
Overvoltage protection:
3 independent overvoltage protections:
1 voltage limiting loop at 28.5 Vdc and 1+1 crowbars at 29 Vdc.
High load fuses breaking capability:
In case of short circuit on the load, the Power supply system delivers a very high peak current (about 500 Amp) for a duration of 0.5 ms.
This characteristic ensures the instant breakage of the protective fuse or circuit breaker. Because of the very short peak current duration, other equipment connected to the load are not
affected by the failure event and continue to operate without interruption.
Functional Safety Management Certification:
G.M. International is certified by TUV to conform to IEC61508:2010
part 1 clauses 5-6 for safety related systems up to and included SIL3.
