The PLH Series - Advanced Linear regulated Laboratory DC Power Supplies

Despite the improvements in high frequency switcher design, Linear regulation still offers the lowest output noise and the best transient response (recovery time from a sudden current step).

It also offers the most benign stability characteristics when driving complex load conditions.

Low noise

Despite its high output voltage of up to 250 volts, the linear regulation of the PLH series ensures low output noise of below 2mV rms in CV mode and below 10uA rms in CI mode (<1uA on the low current range).
