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. |
