- Conversion of AC/DC voltage to a stable DC voltage.
- Stable operation over a wide range of input voltages without reducing output-voltage characteristics.
- Reliable start-up of loads with high input capacitance (operator panels, modems, etc.).
- Protection against overvoltage and impulse interference at the input.
- Protection against overload, short circuit, and overheating.
- Output-voltage adjustment using an internal trimming resistor within ±8 % of the nominal output voltage, with power retention.
- Indication of output-voltage presence.
Main functions
Functional capabilities
Overload protection of the “output-current-limitation” type
Short-circuit protection
In the event of a short circuit, PASB-15/30/60.24 power supplies go into “cut-off” mode until the fault is cleared.
Overheating protection
In the event of overheating, PASB-15/30/60.24 power supplies go into “cut-off” mode.
