INDICATORS: |
| ON LED: |
Power Supply is running |
| REG LED: |
Power Supply is in voltage regulation, in current limit this LED will be OFF. In parallel operation, this LED will indicate that this unit is voltage regulating. |
| LIMIT LED: |
Power Supply is in current limit, the REG LED will be OFF |
|
|
|
|
| POWER SHARE Connector: |
| Used in Parallel Operation, - connect 1 to 1 and 2 to 2 between all operating units (max. 10 units). This will ensure correct regulation and Power Share between units. The unit that is adjusted for the highest Output Voltage will be the regulating unit (REG LED on). |
|
| NOTE: |
Any Output voltage from 5 - 48 VDC max. 20 A , on request. |
|
The EMT 25000 Series will be available with PFC (Power Factor Correction) ultimo 2000, for fullfilling the EN 61000-3-2 / IEC 1000-3-2. |
Parallel Operation: |
| Used in parallel operation, - connect 1 to 1 and 2 to 2 between all operating units (max. 10 units). Unit that is adjusted for the highest Output voltage, will be the unit regulating all other units in parallel operation. This can be observed by the REG LED is ON.
When connecting wires to units in parallel, make these wires from units to common tie point of the same length, to ensure that Power Supplies see the Load with the same Impedance, especially when units are of the high current type.
Note:
Do not connect Power Share Connector 1 & 2 unless unit is paralleled with other units on the powerterminals. If Power Share is connected and terminals are not connected to other units, unit will go in Over Voltage Protection (OVP) mode and shut down.
Above mentioned, will obtain the best Powershare and Control under parallel operation. |
