Ride-Thru Voltage Regulators

Bonitron Ride-Thru Voltage Regulators monitor the drive. If the drive voltage sags or disappears, the Voltage Regulator becomes active and provides power to the DC bus. This allows critical processes to never see the disturbance and can continue operating at full power.

Ride-Thru Voltage Regulator Selection:

• 2-Second Protection
  The M3534R (< 85A) and M3460R (> 85A) Voltage Regulators protect drives and processes from 2-second power sags. They can also be used with energy storage, such as electrolytic or ultracapacitors, to protect from outages lasting up to 2 seconds.

• Up to 4-Minute Protection
  The M3534B (< 85A) and M3460B (> 85A) Battery Voltage Regulators are used with energy storage, such as batteries, to protect drives and processes from outages lasting up to 4 minutes to allow time for generator startup. With seamless power transfer, the M3534B or M3460B (with appropriate components - M3528 Charger and Batteries) allow seamless power transfer from the grid, to Bonitron, to generator.

Display Option:

• Digital Display
  The ASM 3660DD4 is an interactive digital display for the 3534 & 3460 Series that monitors and stores history of power quality issues, including status, voltage, and current.

Battery and Capacitor Chargers

The M3528 Charger charges battery or capacitor banks.

• Charge batteries or ultracapacitors
• AC or DC input available

Charger
The charger, as its name suggests, charges the capacitor or battery bank for energy storage.

Integrated Capacitor Dischargers

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

• Increases maintenance crew safety

Discharger
The discharger uses a properly sized transistor and resistor to deplete the energy stored in the capacitor banks quickly.

Portable Capacitor Discharger

The M3628PD Portable Discharger depletes energy stored in ultracapacitor banks. A voltmeter displays the DC voltage and capacitor bank discharging status.

• Portability allows the use of one discharger on multiple systems
• Self-powered or from supplied 16' 115VAC line cord

Ultracapacitor Solutions

M3528UC Ultracapacitor Energy Storage Modules are designed for simple integration and scalability, and are typically used in conjunction with Bonitron Voltage Regulators and Chargers to provide critical processes with 100% power outage protection.

Energy Storage
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.

The M3528B is a 108V or 120V Battery Bank designed to provide emergency power during 100% power outages for industrial applications. Multiple units can be connected for higher voltages and for longer outage protection.

• Simple connection
• Add benefit of emergency or back up power

Wide Input Range 24VDC Power Supply / Ride-Thru

The M5624 is a 24 volt power supply with a wide range (300 – 1200VDC) input. For backup systems using capacitors or batteries, such as Bonitron 3534 or 3460 Series, the input voltage of the storage can vary widely, yet the local 24V controls for the system will need the same Ride-Thru capability as the drive. The M5624 allows the the same storage system as the Ride Thru to back up PLCs, sensors or networks to allow uninterrupted system operation.

• 300 - 1200VDC input, 24V output
• Ability to use same energy storage for PLC Ride-Thru capabilities

Sag Buffer Ride-Thru for 24VDC

The Bonitron M3532 24 VDC Sag Buffer Module can help equipment ride through irritating and costly sags, while helping provide an orderly shutdown in a more sustained power loss. Using maintenance-free ultracapacitors, the unit can provide anywhere from 700ms to 10 seconds of holdup (load dependent).

• Improved uptime

Some processes may not require uninterruptible power, but just enough power to shut down safely or reset the equipment to a default position during an outage. For these low speed applications the UPD can be undersized to 10-20% of the motor HP, greatly reducing the cost. This is possible because:

Power = Speed x Torque

So theoretically, if you run at one half of the regular speed with the same torque, it will use half of the regular power.

• Ovens - Move system before product or conveyor damaged by heat.
• Extruders - Purge system before solidification
• Hoists - Lower load to a safe postion
• Stamping - Retract feeder mechanisms
