Efficiency as high as 800/o at 300 Watts output. Small size and weight. Constant voltage/constant current. Protected against all overload and short circuit conditions. Built-in over voltage protector to protect against internally and externally generated over voltage conditions. Unit will operate for a period of 40 ms at full load after removal of AC input. o o . very low conducted and radiated interference by optimized filtering. 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. EFFICIENCY Efficiency versus output voltage measureo on MS 030-10 with i0 A toad, R.F.

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 + Remote programming (Only MS modets) waveform). Remote sensing (Only MS models) Separate amplifier terminals enable the output voltage to be regulated at a remote load point, using two sensing leads. 0.050/0 0.050/o S+ S_ Voltage regulation from max. voltage for a * 10 to - 150/o AC line voltage variation. frorn max. voltage for a 1000/o load v
