Woodward V90RD-2540-MBR 9907-1929 ACTUATOR w/REMOTE SERVO

The MicroNet Plus Expansion Chassis may use either single or redundant power supplies.

Each power supply module produces three regulated outputs: 

24 V @ 12 A (max), 5 V @ 32 A (max, derated above

55 degree C external ambient temperature), and 5 V Precharge @ 3 A (max).

A motherboard located on the back of the chassis provides the 

interconnection of the three outputs from each power supply module

into three corresponding power busses: 24 V bus, 5 V bus, and 5 V precharge bus.

The 24 V and 5 V busses are load shared between the two power supply modules.

The 5 V precharge bus is not load shared.

Power output regulation at the motherboard, including line, load, and temperature effects,

is less than ±10% for the 24 V bus, +/-5% for the 5 V bus, 

and +/-10% for the 5 V Precharge bus.

The power supplies can only be installed into slots PS1 (power supply #1) and PS2 (power supply #2). If

redundant power supplies are not needed, blanking plates must be installed in the slots not being used.

Branch circuit fuses, circuit breakers, and wiring must meet appropriate codes and authorities having

jurisdiction for the specific country (CE, UL, etc.). See Table 4-3 for maximum recommended fuse or

breaker ratings. Do not connect more than one main power supply to any one fuse or circuit breaker. Use

only the wire sizes specified in Table 4-3. which meet local code requirements.

Time delay fuses or circuit breakers must be used to prevent nuisance trips.
