Additional Features: Voltage: 0-500V Current: 0.08A Power: 40W Linear 4-quadrant operation FET output stage Preamplifiers for summing and scaling arbitrary input signals Wide bandwidth Voltage and current stabilization with automatic crossover to current and voltage limits The Kepco BOP 500M is a high voltage power source, up to ±500V. The BOP 500M combines the capabilities of fast programmable power supplies with a Class A output stage, which can respond bi-directionally from zero. The BOP 500M can be operated in either a “voltage stabilizing” or “current stabilizing” operating mode (selectable by a front panel switch). They can source or sink up to 100% of their current rating at any voltage setting, depending on the duty cycle. The separate bipolar voltage and current control channels are backed by four independently adjustable (and programmable) limits. Four front panel LEDs tell you whether the unit is operating in the voltage or current mode, or against the voltage limit or current limit. A mode switch on the front panel selects the operating channel.
