COSEL ASIA LTD.
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. |
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.
