Bleeder Control
The SPS power supplies feature a bleeder resistor. When the power is turned off and the
load is disconnected, the bleeder resistor will consume the power in the output capacitor.
Without a bleeder resistor, the output capacitor would continue to be charged, causing
potential danger.
The bleeder resistance can also play a role in smoothing the voltage regulation rate.

Bleeder circuit
Note
The bleeder resistor is turned on by default. In battery
charging applications, make sure to turn off the bleeder
resistor when the instrument is turned off because the
bleeder resistor will discharge the connected battery.
