DC Drives

Chassis mount SCR controls have a free-wheeling diode and feature adjustable accel, decal, current limit, IR comp, min and max speed pots to match applications. The anti-demag features protects PM motors and helps protect the SCR power bridge against direct shorts. The controls have UL and cUL component recognition. Product Overview: Chassis SCR Control Dual Voltage Optional Heatsink – BC143 Heatsink kit is available to increase the drives capabilities to handle a higher output power rating. If the BC143 heatsink is added, the unit will be able to handle up to 1.5 HP at 90 VDC or 3 HP at ...

The anti-demag features protects PM motors and helps protect the SCR power bridge against direct shorts. The controls have UL and cUL component recognition. Product Overview: Chassis SCR Control Includes BC152 Signal Isolator & BC143 Heatsink factory installed NOTE: A Plug-in Horsepower Resistor® and armature fuse MUST be ordered and installed in all versions of BC141 and BC142 controllers. Horsepower Resistors should be selected ...

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 ...

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 ...

Commercial and industrial fans, blowers, pumps, and other machinery that have variable torque characteristics. Prolonged use at low speed can result in significant energy saving. Dripproof motors are intended for use in environments that are relatively clean and dry.
