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-J
Detail of this modification : The input/output terminal is changed to connector type.

Ex .2
Model designation : R25-12-CN
Detail 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.
13	R	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.

MODULAR TYPE

No.	Alphabets	Contents
1	E	Reduce leakage current to the EMI class A lebel.
2	F	The wind directions reversed.
3	G	Leakage current is reduced.
4	K	Low speed fans are used.
5	N	Built-in fan is not used. The fan set externally is used to cool the unit.
6	R	The logic of remote on/off is reversed.
7	T	A fan filter is attached to fan.
8	U	Operation stop voltage is set at a lower value than the standard version.
9	W	A covers are installed on the terminal block of output modules.

Some models are not possible for modification mentioned above. Beside the above, we have some other modification. Please feel free to contact us.
