RIVE PTIONS In 1975, Bonitron began working with the AC inverter drive specialists at synthetic fiber plants to develop speed control systems that could be interfaced to their plant process computers. Since that time, Bonitron has developed AC drive option modules that help overcome many of the problems encountered in applications of modern AC variable frequency drives.

1.2. URPOSE AND COPE This manual is a user’s guide for the Model M3345 Line Regen Control modules. It provides you with the necessary information to successfully install and use the M3345 modules in your application. In the event of any conflict between this document and any publication and/or documentation related to the application, the latter shall have precedence.
Bonitron’s Model 3345 Regen Module is used for regeneration control of any AC drive system that uses a fixed bus system, such as the bus system used on AC PWM drives.
User’s Manual ODEL UMBER The Base Model Number for all Line Regen Controllers is M3345. OLTAGE ATING A 1 digit code represents the 3∅ AC line input voltage to the Regen module. The voltage rating must be selected for the system voltage that will be applied.
M3345 URRENT ETER An “M” in this position indicates the inclusion of a DC Regen current meter with the Regen module. A “0” in this position will omit the meter. A meter is provided as a standard part of all Type-13 JIC chassis modules and Type-1 chassis modules and is optional for all open-chassis modules.

The M3345 must be properly oriented for proper heat flow through the unit. The M3345 must be mounted with the rear surface of the unit to the mounting surface. Unit may be mounted vertically or horizontally as shown in Figure 3-1A.
Never attach the DC bus input of the M3345 to braking terminals on the AC drive, commonly marked “BR”. These terminals are intended for use with an external resistor, and are not directly connected to the bus filter capacitors of the drive.

The M3345 will go into a shutdown mode during such events and resume operation upon return of nominal voltage. The M3345 will also go into the shutdown mode upon loss of any phase of the incoming power.
M3345 4.2.3. NDICATORS 4.2.3.1. URRENT METERING The M3345 Line Regen may come with an ammeter installed. This is an averaging meter which may not deflect the instantaneous current peaks which may be present. 4.2.3.2. OWER NDICATOR The M3345 Line Regen comes standard with a neon power lamp. This lamp is powered by 2 of the 3 phases feeding the AC input.
Adjustments made outside of the factory settings can cause poor performance, reduced system capability, heatsink overheating, or even component failures. Under severe operating conditions, or if the settings have been accidentally or intentionally altered, some minor WARNING! field adjustment may be required. Consult Bonitron prior to making any adjustments.
