1. Preface 1.1 Products Outline B&K Precision models XLN3640/XLN6024/XLN8018/XLN10014 are programmable DC power supplies with single outputs that offer the maximum power output up to 1440 watts (0 -- 36 V/40 A or 0 -- 60 V/24 A or 0 -- 80 V/18 A or 0 -- 100 V/14.4 A). With a 16-bit D/A, A/D converter embedded, the power supplies come with the resolution of 1mV in voltage setting and 1mA in current setting.

Remote Interface communication protocol The communication protocol includes standard SCPI commands and a few proprietary commands which follow the SCPI convention. 6.1 Prefaces The SCPI interface enables users to operate the model XLN3640/XLN6024/XLN8018/XLN10014 supply through a computer or a terminal equipped with IEEE-488.2 GPIB or USB interface. Additionally, it allows remote control and monitoring. SCPI IEEE-488.

characters at the end of each command when programming. 6.3 The Error/Event List SCPI interface can offer an error/event list that contains up to 10 errors/events. Users can read the errors/events through the “error?” command in a first-in first-out manner. Once an error/event is read, the read process will clear it from the memory. To clear all errors/events from the memory, the “*CLS” command is used.

1. Introduction 1.1 Product Summary B&K Precision’s high voltage XLN series are programmable DC power supplies with single outputs that offer maximum power output up to 1560 W. With a 16-bit D/A, A/D converter embedded, the power supplies provide voltage and current resolution of 1 mV and 1 mA. By connecting up to 4 power supplies in parallel, maximum output power can reach 6240 W.
PAGE 102
3) Precise voltage and current measurement Besides the precise output, the high voltage XLN series also offers the capability to measure voltage and current accurately (readback), saving users the additional expense and space for extra measuring instruments. 4) Internal memory and timer function The high voltage XLN series provides internal memory for storage and retrieval of 10 instrument settings. The instruments provide one timer with the resolution of 1 second. The timers are used to time the outputs.
