Appendix A Specifications
– No load—Refers to a resistive load that, when the rated output current flows, makes
the voltage drop to 10% of the maximum output voltage with rated output current or
1 V whichever is higher.
• The specifications of the RMX programmable power supply apply to the rear panel output
terminals.
