Product Description

The IS200CVMBG1A is a device which is called a capacitor voltage monitoring board or CVMB. This is a form of printed circuit board or PCB. The IS200CVMBG1A is a component which monitors voltage across DC link capacitors within Innovation Series drives.

The IS200CVMBG1A gives turbine operators a secondary indication of the presence of voltage when the bridge cabinet doors are opened. This CVMB circuit board features three (3) small lamps which are neon labeled as DS3, DS2, and DS1. These are situated in a horizontal line along of top edge of the IS200CVMBG1A. They can be clearly seen when the doors of the bridge cabinet are opened. These small lamps blink whenever the DC bus contains high voltage of more than fifty (50) volts DC. These neon lamps are controlled by an attenuator network. Both bulb clips and bulbs may be replaced using parts with the numbers 68A944080P1 and 68A7804P4. No test points, fuses, connectors or adjustable hardware are featured on the IS200CVMBG1A. This board can be mounted right onto the DC power capacitor’s terminals with four (4) through-plate mounting holes which are labeled as E1, E2, E3, and E4. E2 and E1 are positioned on the left half of the printed circuit card and the E3 and E4 have been located on the PCB’s right half. The IS200CVMBG1A does not require any input power and dissipates approximately three (3) to five (5) watts of power. The IS200CVMBG1A is a large rectangular printed circuit board which features electronic components such as capacitors and resistors.
