• Semiconductors processed under a "predictable reliability" program to insure long life expectancy. This program includes source coding of all devices, 100% incoming inspection and measurement of parameters beyond operating regions to expose channeling phenomena, surface contamination, safe operating areas, etc.
• Zener voltage references and input stage transistors are preaged and life expectancy extrapolated through l/F noise change techniques during burn-in
• Each power supply operated under maximum stress conditions for a minimum of fifty hours prior to final inspection
• Manufacturing procedures and processes are equal to or exceed those of MIL-Q-9858

The Power Designs 6050C is a regulated DC power source that functionally replaces five conventional power supplies. It utilizes a new regulator technique which provides additional features not available in standard instruments.

Outputvoltage and current ranges cover a broad spectrum of laboratory requirements for both digital and analog applications. Ranging is transient-free and automatic with changes in load and the setting of voltage and current controls. Operation is completely electronic, without relays or manual switching.

The RFI-free regulator system employs linear circuits only. No SCR's, switching transistors or high frequency techniques are utilized. 

Power output capability of the supply increases with increasing AC line voltage. Up to twice rated output is available at line voltages over 105 volts. Useful regulated output at reduced levels is available down to a line voltage of 85 volts.

A flashing panel indicator signals loss of regulation when load demands are in excess of control settings or the AC line voltage is too low to support increased output levels.

The supply may be operated continuously into an overload or short circuit without damage. Regulator efficiency is superior to conventional, wide voltage range, dissipative type systems.

Portable and light, the Model 6050 is designed for laboratory bench or rack use. A bail/carrying handle assembly permits tilting of the front panel for viewing ease.
