BOP HIPWR 031912 1-1SECTION 1 - INTRODUCTION1.1 SCOPE OF MANUALThis manual contains instructions for the installation, operation and servicing of the BOP seriesof 1000 Watt rack-mounted, 4-quadrant bipolar, programmable, voltage and current stabilized d-c power supplies manufactured by Kepco, Inc., Flushing, New York, U.S.A.NOTE:This manual does not apply to units with Firmware Rev less than 2.0.1.2 GENERAL DESCRIPTIONThe BOP Series (Figure 1-1), hereafter referred to as BOP, are true 4-quadrant programmablevoltage and current power supplies, meaning they are capable of both sourcing and sinkingpower. These bipolar power supplies pass smoothly through zero without switching to providetrue ± voltage and ± current. These BOP power supplies use switch mode technology for lowdissipation. A bi-directional, isolating, a-c input power factor correcting (PFC) circuit recuperatesenergy sinked from an active load and sends it back into the line to maintain low dissipation.These BOP power supplies are controlled digitally from a menu-driven front-panel keypad orone of the standard remote digital interfaces (GPIB or RS 232) to set voltage and current andthe four protection limits (+voltage, –voltage, +current and –current.) A front panel rotaryadjuster allows real-time adjustment of the output. A large LCD displays the settings, mode andthe actual output voltage and current. Additionally, these BOP models can be remotely con-trolled by an analog ±10V input for the main channel (voltage or current), and a +1 to +10V inputfor the limit channels.BOP models are suitable for driving inductive loads such as large magnets or motors, and forexercising batteries. They are also suitable for characterizing solar cell arrays, and poweringmany electrochemical reactions.1.3 SPECIFICATIONSTable 1-1 below indicates parameters that vary for different 1000 Watt BOP models; Table 1-2lists general specifications that apply to all 1000 Watt BOP models.TABLE 1-1.

Otherwise the overvoltage protection will shut down the power supply.
