FEATURES & BENEFITS
1/8 to 1/2 Hp
Half Wave SCR DC Regen
n 4Q reversing: Regenerative/4 quadrant drives have the ability to perform quick, contactorless reversing on-the-fly!
n MM footprint (RG25U only): An extremely compact size in an industry standard mounting footprint.
n Speed range and regulation: 3% regulation over 50:1 speed range.
n User adjustable calibration pots: IR compensation, max speed, forward torque, reverse torque and deadband.
n Stopping modes: Regenerative braking (N.O.).
n Screw terminal block (RG51UA) and spade terminals (RG25U): Easy to terminate wires.
Regenerative drives, like Minarik’s RG25U and
RG51UA, control brush-type DC motors for applications
that require bi-directional variable speed and smooth
motoring or braking torque in either direction of rotation. The RG25U and RG51UA are ideal for OEMs:
These half-wave SCR drives deliver 1/8 through 1/2 Hp.
The compact size and low-cost distinguish them from
other regenerative drives on the market. The RG25U
drive uses the same chassis as our popular single-quadrant SCR drive, the MM23001C. It is one of the smallest
1/2 Hp Regens on the market.
Applications with overhauling loads, rapid deceleration,
basic positioning, reversing and braking benefit from
these versatile regenerative drives. These drives are ideal
for low duty cycle applications.
