DC Drives

These are General Purpose drives designed for use with Permanent Magnet or Shunt wound DC motors. NEMA 1 enclosed drives are suitable for most industrial applications. The NEMA 4X controls are best suited for washdown or outdoor installations or for extremely dusty applications. Chassis only drives are available for building into equipment, machinery or existing enclosures. Most controls have a dual voltage switch allowing the control to be used with either 115 volt or 230 volt, single-phase, input power at either 50 or 60 Hz service. It is important that the proper voltage motor be ...

MERZ has long been the industry standard in UL certified switches. MERZ cam switches are second to none for quality and reliability. Springer Controls-MERZ switches are available in models from 16 amp to 125 amp. These UL certified switches are suitable for residential and industrial applications. This item is a 4-screw, front-panel mounting-cam switch. Both the switch and the handle are attached to the panel or wall by these four screws (included.) Cam switches, according to their contact arrangement, are fitted with switching chambers with 1, 2, or 3 (series 111 only) double interrupted ...

Blower and Mounting Kits for DC Integral Hp Motor Catalog No. Ending With "P" Features Tach mounting kits supply adapter, coupling, accessory shaft and mounting hardware Allows mounting to 8.5 inch accessory face on most large DC motors Application(s) Allows addition of DC, AC and digital tachometers to large DC motors for closed-loop operation

Features BC154, BCWD140 and BC160 are non-regen controls with reversal by means of switching the armature leads (BCWD140 has a forward/brake/ reverse switch mounted). BC254 is a line regenerative SCR control that can drive the motor to a timed stop. BC354 is a PWM control that provides lowripple DC power to the motor allowing more Hp when used with a 130 or 260 VDC motor. All offer a choice of armature or tachometer feedback and a speed or torque mode. No Hp resistors are needed for these controls, current is jumper selectable. BC154, BC160, BC254 and BC354 are painted black and come with ...

Regen controls are designed to easily operate the motor in forward and reverse directions without motor lead reversal. A separate set of SCRs is used for each direction. With a regen control, stopping is controlled by using the motor's regenerated voltage sent back to the AC line. Features Field power supply allows use with shunt wound DC motors as well as permanent magnet motors Adjustable accel, decel, current limit, IR comp, min and max speed Current limit indicating LED 5K speed pot for speed control Anti-demag circuit protects PM motors and helps protect the SCR power bridge against ...
