Bently Nevada 3300/14-01-20-02 DC Power Supply Module

Description

The Bently Nevada 3300/14-01-20-02 DC Power Supply provides reliable, regulated power to up to 12 monitors and their associated transducers in a 3300 Rack. It is installed in the left-most position (position 1) of the rack and supports primary voltage operation of 20-34 Vdc or 90-140 Vdc. The module converts input voltage for use by monitors in the rack, ensuring that the system operates within the specified voltage range. Over-voltage and under-voltage protection circuitry are included to shut down the power supply if the input voltage falls outside of the specified range. It will return to normal operation once the voltage is within the acceptable range. Additionally, the unit is fuse-protected against reverse polarity power hookup and power inputs exceeding 140% of the maximum rated input voltage.

Warning
Transducer field wiring failure, monitor failure, or loss of primary power can result in machinery protection loss, leading to property damage and/or bodily injury. It is strongly recommended to connect an external annunciator to the OK relay terminals.
