Standard Options

Cosel is dedicated to providing common options or additional features to Cosel standard product.

These standard options or additional features will be identified by an alphabetic value. (Please see example below)

Example 1
Standard part designation:	R25A-5
Option designation:	R25A-5-J
Change to unit: Terminal bock at both input and output will be changed to connector type.
Example 2
Standard part designation:	R25A-5
Option designation:	R25A-5-CN
Change to unit: PCB is conformal coated and case cover is attached.

The following list of optional units available by power type.

UNIT TYPE & RUGGED PCB TYPE:
No	Value	Contents
1	A	Shorting V2(GND) and V3(+) reverses polarity of V3 (LCC only)
2	C	Except certain devices (e.g. potentiometer), PCB is conformal coated
3	D	Output voltage is set at requested voltage within output voltage adjustable specified range
4	F	Fan or Fan unit is added to power supply
5	G	Decrease leakage current by reducing the value of earth capacitor at input filtering circuit
6	H	Changing the over-current activation point to make peak output current possible
7	I	Making series operation available on units that series option is not standard
8	J/Jn	Terminal block changed to connector type at both input and output/case cover added
9	L	LED for output indicator
10	M	Silicon rubber affixed to certain components on the PCB
11	N	Case cover is attached to power supply
12	P	Operative over-current point is set to 90-100% of rated output current
13	R	Output remote on/off is made possible/if already possible R signifies reversed logic
14	SN	Chassis and cover are attached to Rugged PCB
15	T	Terminal block changed from horizontal to vertical position
16	V	Twisted wire is led from power supply to attach output voltage setting potentiometer externally
17	Y	Potentiometer is added to units
On Board Type:
No	Value	Contents
1	F	Heat sink added
2	G	Capacitor between Input and Output is removed
3	L	Input and Output pins are shortened
4	R	Remote On/Off logic is reversed
5	S	Case connect pin is cut
6	T	Through-hole mounting on units that come tapped as standard unit
7	M	Tapped mounting holes on units that come through-hole as standard unit
Modular Type:
No	Value	Contents
1	E	Reduce leakage current to EMI class A level
2	F	Reversed airflow
3	G	Reduced leakage current
4	K	Low speed fans
5	N	Fan unit removed. Extra airflow notch in top of chassis for external airflow.*
6	R	Remote On/Off logic Reversed
7	T	Filter attached to fan unit
8	U	Over voltage shut off is set lower than standard
9	W	Covers are installed on the output terminal blocks

* Forced air must be supplied by customer

NOTE: Not all options available for all series or all models in a series. Some options not listed. Please refer to the specification PDF or contact your local Cosel USA Office if you need more information.
