More Information

Overview Manuals Four-Quadrant Use Load Stability Rack Planning Application
  • ±20 V and ±20 A four-quadrant output
  • 400 W linear bipolar operation
  • Local and ±10 V remote analog control

BOP-20-20M is a high-speed bipolar source for applications that require controlled positive and negative voltage or current.

Its four-quadrant output can drive a load and absorb returned energy, enabling dynamic simulation and actuator testing around zero.

Correct deployment depends on load stability, rack ventilation, AC input configuration and verified voltage/current limit settings.

Availability, condition, price, and shipping time for BOP-20-20M are confirmed during quotation.

  • Output passes smoothly through zero
  • The unit sources and sinks rated current
  • Voltage and current loops cross over automatically
  • Capacitive loads may require slower feedback
  • Inductive loads need current-loop compensation
  • Cabling and return paths affect dynamic behavior
  • The 400 W model uses full-rack width
  • Forced-air exhaust exits at the rear
  • Rear connectors require additional depth clearance
  • Magnetic actuator and coil testing
  • Battery and power-system simulation
  • Four-quadrant component characterization
Description
BOP-20-20M operates as a high-power bipolar operational amplifier for sourcing and sinking current through zero without polarity switching.

Separate voltage and current control channels provide automatic crossover, while local controls and a ±10 V analog command support static or dynamically varying output.

Installation must account for full-rack depth, forced-air exhaust, rear connector clearance, AC input current, load stability and the correct voltage/current limiting setup.

Technical notes
KEPCO BOP-20-20M requires full-rack support, rear airflow, correct AC tap selection, adequate branch current and load-specific stability compensation before four-quadrant operation and final load testing are commissioned.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can KEPCO BOP-20-20M both source and absorb current?
Yes. It is a four-quadrant unit rated to source and sink through the full ±20 A range when load and thermal conditions are satisfied.
Why can KEPCO BOP-20-20M oscillate with a capacitive load?
The high-speed bipolar design has no large output storage capacitor; capacitive loads may require feedback compensation and reduced bandwidth to remain stable.
What rack space and clearance does KEPCO BOP-20-20M require?
Allow a full 19-inch rack width, the official 51.0 cm chassis depth, about 6.35 cm for rear connectors and unobstructed rear exhaust.
What AC supply capacity is needed for KEPCO BOP-20-20M?
Select the documented input-voltage tap and provide a branch circuit that can support approximately 11 A at 125 VAC under worst-case source operation.
How is KEPCO BOP-20-20M controlled remotely?
A ±10 V analog command can program the output, and compatible internal interface cards may add supported digital control; confirm installed options from the label.
What should be checked before connecting an inductive load to KEPCO BOP-20-20M?
Review current-mode stability compensation, stored-energy behavior, cabling, protection and the load's return path before energizing the circuit.
How should KEPCO BOP-20-20M be accepted after repair or replacement?
Verify zero output, both polarities, voltage and current limiting, source and sink operation, meter indication, fan airflow and stability with the intended load.
