Ride-Thru Voltage Regulators (Use for Sags or add Capacitors for Outage Protection)
	The M3534R and M3460R Boost Regulators regulate the DC bus inverter during a voltage sag event. As the incoming voltage level drops, the M3534R or M3460R becomes active to boost the rectified DC up to the minimum level needed by the inverter. For 100% outage applications the M3534R or M3460R becomes a capacitor voltage regulator when used in with capacitors. Exceed SEMI-F47 specification Low maintenance Long life expectancy
M3534R 5 to 50kW Drives		M3460R 50 to 1300kW Drives

Ride-Thru Voltage Regulators (Add Batteries for Outage Protection)
	When used with a battery bank, the M3534B and M3460B Battery Voltage Regulators provide DC bus support for up to 15+ minutes during a 100% power outage as well as AC line voltage sags for AC drive systems using VFDs. The M3534B and M3460B solve the “voltage drop” problem associated with battery banks in back-up situations by regulating the battery bank voltage and boosting it as it drops. Up to 15+ minute outage protection with batteries

Portable Capacitor Discharger
	The M3628PD Portable Discharger depletes energy stored in ultracapacitor banks. A voltmeter displays the DC voltage and capacitor bank discharging status, which combined with a fused positive DC link, increases safety for cabinet maintenance. Includes IGBT switch and resistor 16 - 18ft leads/cords Portability allows the use of one discharger for multiple Ride-Thru systems Self-powered or from supplied 16' 115VAC line cord

Battery Solutions

The M3528B is a 108V or 120V Battery Bank designed to provide emergency power during 100% power outages for industrial applications. The M3528B is used with the M3528 Charger and M3534R Boost Regulator as part of a complete Ride-Thru System for fixed bus, variable frequency drives.

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

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

Display Monitoring Solutions
	The M3660DD3 gives users real time information about system functions and monitors present values of the bus and line voltages, currents, and records power quality and Ride-Thru events, including time, duration, and voltage levels.

Open Battery Cell Bypass
	The M3528D bypasses an open battery used in series high voltage battery strings. When used with Bonitron voltage boosters, the diode allows current to bypass the open battery while the booster compensates for the drop in voltage. The M3528D indicates which battery is bad so that only the bad battery needs to be replaced.
________________________________________________________________________________________________________________

Battery String Monitor
	If a battery discharges too far, individual cells may change polarity, causing permanent damage to the battery, reducing its lifetime. Batteries, capacitors, and any other system can be damaged by the voltage rising too high. The M3528M2 voltage monitor is designed to monitor DC voltage levels and signal the user if the voltage departs a set range.
________________________________________________________________________________________________________________

Battery Cell Monitor
	The M3528M4 monitors a series of 12V batteries and signals the user if one or more of the batteries’ voltages fall below the undervoltage set point, exceeds the overvoltage set point, a blown fuse, or over temperatures exist.

Diode Sharing Modules

Bonitron’s M3460D Diode Sharing Modules provide blocking diodes that isolate the drives from each other while still establishing a shared, common Ride-Thru bus. This can be used on equally sized and loaded drives within a system, allowing the use of a single boost regulator with more than one drive.

Isolate drives while sharing common Ride-Thru bus

What is Ride-Thru?

Bonitron Undervoltage Ride-Thru Solutions include a DC voltage conditioner that monitors the AC line. If the AC line voltage sags or disappears, the Ride-Thru system becomes active and provides power to the DC bus. Therefore, critical processes never see the disturbance and can continue operating at full power. Thanks to Bonitron's parallel connection, low standby power and long product life can be expected. Plus, process reliability isn't compromised like with in-line UPS systems.

Sag

Deep Sag Correction - Up to 2 Seconds

Bang for Your Buck!

Bonitron Sag Solutions are the cost effective way to make sure your critical process never sees power disturbances. While some applications experience complete power outages, in most parts of the world sags are the most common culprit of process power disturbances.

Sag Solutions include a voltage booster that allow your process to continue running at full power during a voltage sag. If future needs require energy storage, a simple add-on can easily be installed.

No energy storage necessary

Increased Confidence!

While many power disturbances are only caused by sags, there are those complete outages that can wreak havoc on a critical process. Bonitron Capacitor Solutions allow your process to continue to run at full speed for up to 2 seconds during a complete power outage.

Bonitron Capacitor Solutions use long-life capacitors and include a discharger for increased safety and quick cabinet access.

No Power? No Problem!

Bonitron Battery Solutions are the economical method of providing DC bus back-up power for up to 15 minutes. Bonitron Battery Solutions are ideal for dark starts where no initial power is available or to hold up processes until there's time for generators to start.

Bonitron Battery Solutions can be purchased with batteries, or batteries can be sourced locally to reduce shipping costs.
