Bonitron M3628 Capacitor Discharger

Bonitron > Products > Maintenance > Dischargers > M3628

The M3628 Series discharges capacitor banks to safe working levels quickly, allowing work on the system to begin in seconds, rather than hours.

A complete M3628 system consists of a M3628T Transistor and M3628R Resistor. The discharge cycle can be started or stopped at any time via an optically coupled enable input, and units may be paralleled for faster discharge times or for larger energy banks.

Portable units are available for installations with multiple capacitor banks.

Features

LED indicators
Overtemp feedback contacts
Self-powered

Advantages
