COMPARISON WITH CONVENTIONAL POWER SUPPLIES
The new MS power supplies use high frequency energy conversion and regulation, which means a considerable size and weight reduction of transformer and capacitors. They also offer a large improvement of efficiency. Another advantage is a larger allowed AC input voltage variation. A disadvantage of the switching regulator, compared with the series pass regulator, is a worse specification of regulation, ripple and recovery time. However for many application. tf'"." specifications are still
suff icient.
CONSTANT VOLTAGE/CONSTANT CURRENT REGULATION
CV/CC ioad characteristrc
The MS and MST power supplies can be used either as a constant voltage source with a limited current or as a consiant current source with a limited open voltaqe. The change of mode occurs sharply at the crossing of the voltage and current setting.

Voltage control
MST models 10-turn potentiometer, resolution 0.020/0. MS models 20-turn screw driver adj., resolution 0.30/0. The output voltage can be programmed externally by a variable resistor of 0-5 KOhm (0-10 KOhm for MS 060_5). Programming with an external voltage (1 V per V) is also possible. At full load the programming speed is 300 V/sec. (measured with a trianqular

Extension of the regulating loop
Regulated power supplies, as feedback controlled devices, are de signed to control the e1e ctrical parameter s of voltage or current. The regulating loop can also be extended to include a variety of physical elernents such as position, speed, ternperaturer pressure, chernical activity and the like. Assurning the necessary transducers and sensors, servo-like control rnechanislr's can easily be constructed using D-C regulators as translators, sulTtlrlers, arnplifiers, followers.
