Modified Power Supply

Cosel is dedicated to providing support for customers requiring additional features or modifications to catalog products.The factory will assign a special identification alphabet to modified units.Please feel free to contact us with your requirements.Following is the list of modified units available:

  • Ex .1 Model designation : R25-5-JDetail of this modification : The input/output terminal is changed to connector type.
  • Ex .2 Model designation : R25-12-CNDetail of this modification : PCB is coated and case cover is attached.

■ Alphabets of modified units and it’s contents of modification ■

UNIT TYPE

No. Alphabets Contents
1 A Power supply that V2(GND) and V3(+) were made common.
2 C Except a certain device(e.g.potentiometer), PCB is coated.
3 D Output voltage is set on request within the output voltage adjustable range.
4 F Fan or Fan unit is additionally included in power supply.
5 G Decreasing a leakage current by reducing the value of earth capacitor at input filtering circuit.
6 H By changing the overcurrent operative point, and make it possible to get peak output current.
7 I Modified as series operation possible those which are not possible to make series operation.
8 J /Jn Terminal block at input/output is changed to connector type.
9 L LED for output confirmation is added.
10 M Silicon rubber is attached to those power supply.
11 N Case cover is attached to those open frame type power supply.
12 P Operative overcurrent point is set to 90-100% of rated output current.
13 R Output remote ON/OFF is made possible.
The logic of output remote ON/OFF is reversed.
14 SN Chassis and cover is attached to PCB type.
15 T Terminal block is changed from horizontal to vertical position against PCB for screwing.
16 V Twisted wire is led from power supply to attach output voltage setting potentiometer externally.
17 Y Potentiometer is attached additionally to those which is not available to standard power supply.

ON-BOARD TYPE

No. Alphabets Contents
1 F Power supply with the addition of a heat sink.
2 G Capacitor between Input and Output is removed.
3 L Input/Output pin are shortened.
4 R The logic of output remote ON/OFF is reversed.
5 S Case connecting pin is cut.
6 T Mounting holes are through-hole type.
7 M Mounting holes are tapping-hole type.
