HydroDrive™ Variable Speed Drive for Metering Pumps

The HydroDrive DC SCR Variable Speed Drive is specifically designed for use with metering pumps

Specifically designed for use with metering pumps, the HydroDrive™ DC SCR Variable Speed Drive is a NEMA 4X (IP-65) variable speed motor control for shunt wound or permanent magnet motors. Its rugged, die cast aluminum housing is protected with an acrylic coating for the ultimate in corrosion resistance, making it suitable for applications requiring washdown, watertight integrity. All switches are sealed with rubber boots, and the manual speed adjustment potentiometer incorporates a shaft seal.

Standard Features:

  • On/Off AC Line Switch
  • Start/Stop Run Switch
  • Auto/Manual Selector Switch
  • Manual Speed Potentiometer
  • Electronic Overload Protection
  • Built-in Armature Fusing
  • LED Indicator Panel
  • Signal Isolation

Notes:

  1. Maximum recommended output is 90 VDC for 115 VAC and 180 VDC for 230 VAC. Exceeding these output voltages may cause a reduction in load regulation performance.
  2. For shunt wound motor with lower voltage field, use L1 and F1 connection.
  3. For Armature Feedback, regulation is % base speed. For Tachometer Feedback, regulation is % set speed.
  4. Regulation is % base speed at full load, 100-130 VAC.
