Description

Edulab Laboratory Power Supply
The Edulab 0-15V power supply has proved to be
extremely popular and the ideal choice for physicists worldwide. It is simply the most advanced power pack
available today and with the 5 year warranty it’s a safe
investment.

This power supply provides stepped voltage of 0-15V in one volt steps for both
AC and slightly smoothed DC. A special key lock (all units have identical keys) allows the voltage to be locked to a particular level or to a maximum (ceiling).  Long switch lift time means that voltage can be switched safely at full load without serious contact wear.  Continuously rated output of 8.5A, AC or DC , or added sum of 8.5A

The set ceiling or locked voltage will be memorized, even
if the unit is switched off and on again.  Fully protected, secondary by high speed, micro-processor controlled, resettable electronic trip. Over-current is measured and timed for cases of serious overload and slight overload to decide tripping time This avoids over-sensitive tripping in cases of initial heavy current surge, for example when using lamp bulbs.

Slow-blow fuse protection for primary transformer.  Additional Thermal Trip protection for transformer.  Schottky barrier diodes are employed for rectification with less voltage drop and power waste

Please note that these are not regulated power supplies.

Technical Specifications

Specifications:-

Dimensions:- 208 mm x 155mm x 115mm (W x H x D)
Input voltage:- 230V ±5%
Output voltage:- 0-15V AC at full load
Slightly smoothed DC (by 2200µF output capacitor) gives
practical r.m.s values of 0 -15V at no load.

 

"The 605-055 are unregulated power supplies so, it is normal for the output voltage to be higher than selected when they are under low or no load. It will approach the selected value as the load approaches full rated current. The digital display on the front of the unit only indicates the transformer tapping selected; it is not a voltmeter connected to the output. The discrepancy between the selected and actual voltages will be larger for the DC output under low loads as this output is a rectified version of the AC output. At very low currents the rectifier and smoothing capacitor will be picking the tops off the AC waveform so the DC voltage will be close to √2 times the RMS AC voltage."

97.3% of orders will be dispatched in 3-5 working days. Express next day delivery is available for in stock items but this incurs a small charge.
Some goods because of their size, weight and supply route will incur a larger delivery cost and will have a longer lead time. Edulab will contact you to inform you of this.
Customers from Europe and the rest of the world will be contact by one of the Edulab team to discuss delivery costs and lead times. We reserve the right to contact the customer prior to despatch of goods to inform of a change in cost of delivery.
