4970 DC to DC Drive Specifications
The DC adjustable voltage drive(s) shall be Hubbell Type 4960 and shall convert standard DC power to adjustable voltage DC power to control DC series or shunt motors. The drive shall be sized or duty rated with a full load ampere capacity equal to or greater than the full load current value of the connected motor or motors.The 60-minute rating shall be used to determine the full load current value for shunt motors, and the 30-minute rating shall be used to determine the full load current value for series motors. The drive power devices shall provide a minimum overload capacity of 150% of full load current for one minute and 200% full load current for three seconds. The drive power devices shall be connected to provide static voltage and current reversals. The drive shall provide continuous current, type B control, and shall accept regenerative power returned from connected loads.
