Energy Storage


M3528UC M3528
Bonitron Energy Storage Modules are designed for simple integration and scalability, and are typically used in conjuction with Bonitron Voltage Regulators and Chargers to provide critical processes with 100% power outage protections. Energy storage is a bank of either ultracapacitors or batteries.Ultracapacitors are used for energy storage for durations less than 2 seconds. Batteries are used for energy storage for durations longer than 2 seconds.

M3528B Resevoir

The M3528B Battery Energy Storage Modules are designed for simple integration and scalability, and are typically used in conjunction with Bonitron Battery Voltage Regulators and Battery Chargers to provide critical processes with 100% power outage protection or offer "dark start" capabilities. M3528B Battery Modules are offered in 108V and 120V and can be connected in series or parallel to be used with 230 or 460 VAC systems.

M5628 Ultracapacitor Cabinet

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.

m3162EC Bus Filter

The M3612EC is a filter capacitor bank for a common DC bus drive systems. The drives can be either servo or variable frequency drives intended for use with common bus capacitors.
