The M5628 Ultracapacitor Cabinet along with our M3460 NEMA-1 Ride-Thru module allow your VFD to maintain full power through sags and outages so your process never sees a disturbance. The M5628UC also comes with an option to include an internal charger and/or a built in discharger. If you include the M5628 Charger, your cabinet will be installed with an ASM 3660 Digital Display unit with the ability to monitor the status of the unit.
