PMB703-3

PMB Series

The PMB series is American Control Electronics's choice for a 4Q PWM series. PMB Series drives can control motors rated for 90, 130, 180, or 240 VDC range with either a 115 or 230 VAC line input, up to 7 amps or 1.5 HP. With the use of on-board trim pots, you can quickly set the forward and reverse maximum and minimum speeds, acceleration and deceleration rates, motoring and regening current limits, and IR compensation. Each drive is designed with built-in isolation so it can be commanded with a wide range of analog inputs. The drive even provides logic for dumping current to a braking resistor when it's reached it maximum regenerative capacity. The microprocessor based design means it can be modified to fit OEM specific applications.

Features

  • Microprocessor Based: Allows custom programming for OEMs
  • Auto Ranging Input: No input voltage switches to set
  • Accepts AC or DC Input: Can accept 80-340 VDC or 90-240 VAC input
  • Doubler Mode: Drive can double the internal voltage to allow for 240 VDC output with only a 115 VAC input
  • Stopping Modes: Enable (N.C.) can be set for coast or brake. Can be used for rapid starting and stopping
  • Isolated Logic: Allows floating or grounded 0-10 VDC or 4-20 mA signals
  • Dumb Circuitry: Internal circuitry for the hookup of an external dump resistor
  • Quadrature Encoder Option: For OEM applications, the drive can be programmed to follow quadrature encoder feedback without any circuitry changes
  • Thermally Protects: Drive recognizes when overheated as a result of frequent overload. It first flashes a warning code and will trip if condition persists
  • 4Q Reversing: Regenerative / 4-Quadrant drives have the ability to perform quick and contactorless braking and/or reversing-on-the-fly
  • Diagnostic LEDs: Power, Status(Undervoltage, Overvoltage, Short Circuit / Current Trip, Overheat Warning, Overheat Trip)
