Solid State Brake Contactor

The SSB is a specially engineered product for use on new Smart-Move^TM drives that will save panel space, wiring and installation time by eliminating the need for an a.c. brake contactor.  The small footprint of the Smart-Move^TM  is not compromised since the SSB mounts easily within the drive. Easy to attach and easy to wire. The advantage of this option is that no contactor for switching a "high" voltage AC brake is needed on a control panel - single phase only.  The unit is available in both a 208-230 VAC version - SSB1 and a Universal  Voltage version 208 through 460 VAC - SSB2. The option can be attached at the factory or in the field if required.  For use on drives built after April 1998.

Selection of Product

Never exceed either the rated horsepower or the Full Load Amps. Horsepower is approximate using NEC charts at 1800rpm. Multiple motors can be controlled on the same motion (use total HP and total amps). Go to the next size if either is exceeded. ADD "H" to part number for a hoist pre-set control (load brake style hoist). For safety do not use this series of product on hoisting without internal Weston type load brakes. If mechanical holding brake on the hoist is held open does the load drift down on the hoist? If it does drift, you definitely do NOT have an internal load brake or it is not functioning properly. Thoroughly read the manual and follow all the instructions and safety precautions.

(A) SIZE  (SEE CHART)
The  designation [ ] are past sizes. The designation ( ) are approximate future sizes. The size in bold are the sizes available as of the printing of this brochure. The other physical sizes are in order of introduction. The reduced size models may be available without notice. SEE UPGRADE PATH PHILOSOPHY INFORMATION.

(B) REGEN CIRCUITRY INCLUDED
Unique to PE is all drives include the regeneration electronic transistor circuitry as standard and does not need to be purchased separately. The EXTERNAL regen resistors are purchased separately.

(C) REGEN RESISTOR
Horizontal motion control applications for bridge/trolley monorail etc., will require an external regen resistor bank (sold separately by PE) unless it is noted as being INTERNAL to the drive. PE external resistors are designed with special electrical safety housings. Un-enclosed  resistors (such as those used for reduced voltage starting applications) are dangerous and not safe for use with any variable speed drive and should never be used. Unlike generic drives, PE has designed into its drive's the electronic portion of the regeneration circuitry. Most Weston Load Brake style hoists do NOT require regen resistors with PE drives (unique PE feature). PE discourages the use of external regen resistors on load brake hoists. Many worm gear hoists, with PE drives, may not require regen resistors ballasts either.

(D) CONTROL SIGNAL INTERFACE
PE Drives are designed for overhead crane applications and they do not require separate interface cards. The control signal interface is built into the drive (not a separate add-on card or parts to loosen). 115vac is standard; all other voltages are available, including 24vac and 48vac or dc.

(E) STARTING TORQUE
PE drives have the highest starting torque of any drive in the industry of 300%. Most generic drives are only 180% or less.
