Section 1. Features and Specifications
Description
The Analog Programming (APG) Interface is an internal option card for analog
programming of XT and HPD Series DC power supplies with a 0-10Vdc
programming source or a 0-10kΩ resistance. A 25-pin female DSUB connector on
the unit's rear panel enables connections to the card.
Features
• Programming output voltage and/or current limit using a 0-10Vdc programming
source or a 0-10kΩ resistance. Externally adjustable offset and range.
• Fixed programming of output voltage and/or current limit using an available
10V reference (10mA max source)
• 0-10V readback of output voltage and current with externally adjustable offset
and range
• Status signals for programming mode, operating mode, OVP (over voltage
protection) flag, and output fail flag
• Adjustable OVP with reset and flag
• TTL shutdown with selectable positive or negative logic
• Tracking for multiple supplies of the same output
