Fig.5-5: Parallel operation with Remote sensing

CAUTION Make sure that the connection between –V terminals is reliable to avoid disconnection during operation. Disconnection may cause damage to the power supply.

NOTE

With local sensing it is important to minimize the wire length and resistance. Also the positive and negative wire resistance should be close as possible to each other to achieve current balance be- tween power supplies

5.16 DAISY-CHAIN CONNECTION

It is possible to configure a multiple power supply system to shut down all the units when a fault condition occurs in one of the units. When the fault is removed, the system recovers according to its setting to Safe-start or Auto-restart mode.

Setup switch SW1, position 5 should be set to its DOWN position to enable the Daisy-chain op- eration. Other SW1 positions can be set according to the application requirements.

If a fault occurs in one of the units, its PS_OK signal will be set to a low level and the display will indicate the fault. The other units will shut off and their display will indicate “SO”. When the fault condition is removed, the units will recover to their last setting according to their Safe-start or Auto-restart setting.

Fig.5-6 shows connection of three units, however the same connection method applies to sys- tems with a larger number of units.

5.17 FRONT PANEL LOCKING

The front panel controls can be locked to protect from accidental power supply parameter change. Press and hold the PREV button to toggle between “Locked front panel’ and “Unlocked front panel”. The display will cycle between “LFP” and “UFP”. Releasing the PREV button while one of the modes is displayed, selects that mode.
