Rima Engineering Corporation

Sci-tech DC to DC Power Supply Model 20501 comes from the range of high wattage output power
supplies that are designed for simple laboratory experiment applications.
These range of power supplies are mechanically designed for ‘Benchtop’ application.
User safety to meet all international standards are the main specification as per CE norms for full
range of our power supplies.
Output I: DC
Fixed output of 5 Volts DC output is available at continuous 1A & which is regulated output at full load
conditions. The output is fully overload protected through internal fold-back circuit.
Output is available on Red & Black terminals.
Input Terminals:
As seen on the front panel, input DC terminals are available on ‘Red’ & ‘Black’ terminals.
Power Supply construction:
Power Supply construction is as per international standards, that can be used as table top bench
instrument.
Accessories provided:
1. Instruction Manual.

Sci-tech AC & DC Output Power Supply Series are a range of high wattage output power supplies that are designed for laboratory applications. These power supplies offer 0 to
12Volts or 24Volts or 30Volts continuously variable AC output as well as rectified and fil- tered DC output at full load rated capacities. Both AC as well as DC outputs are available si- multaneously. Overload trip switch activates at maximum total current drawn at AC as well
as DC outputs.

Unique feature of these range of power supplies is that ALL OUTPUTS ARE SIMULTANEOUSLY USABLE AND ARE FULLY PROTECTED.

Another unique feature of these power supplies is the toroidally double wound variable transformers that eliminates use of two transformers thereby improving on efficiency, re- duced heating and compact size of the power supplies.

User safety to meet all international standards are the main specification as per CE norms for full range of our power supplies.

Output I:
Continuosly variable from DC output is available at maximum load current thoroughly a full wave bridge rectified and smoothed using appropriately designed capacitance value. Optionally, the DC output can be offered with further filter circuit to reduce noise/ripple con- tent. Regulated DC outputs can also be offered optionally.

The output is fully overload protected through overload trip switch.Output AC/DC switch- able Digital or Analogue Voltmeters and Ammeters offered as per customer requirements.

Output II:
Continuously variable from AC output is available at rated load current.The output is fully overload protected through re-settable trip switch.Output AC/DC switchable Digital or Analogue Voltmeters and Ammeters offered as per customer requirements

Output Terminals:
As seen on the front panel, DC outputs are available on red & black terminals. AC out- puts are available on Blue terminals. Earthing green terminals must be used to earth pro- tect the outputs.

The terminals provided on the front panel are as per the new European standards, spin- free, shrouded & fully shock protected.
