Output

Power supply

• TRMS 3-phase over and under voltage,

phase sequence and phase loss monitoring relays

• Detect when all 3 phases are present and have the

orrect phase sequence (except for N versions)

•

Available versions (W4) supplied between phase and

eutral

• Detect if all the 3-phase-phase or phase-neutral volt-

ages are within the set limits

• Upper and lower limits separately adjustable

• Measure on own power supply

• Selection of measuring range by DIP-switches

• Adjustable voltage on relative scale

• Adjustable delay function (0.1 to 30 s)

• Output: 8 A SPDT relay N.E.

•

For mounting on DIN-rail in accordance with

IN/EN 50 022 (DPB01) or plug-in module (PPB01)

• 22.5 mm Euronorm housing (DPB01)

or 36 mm plug-in module (PPB01)

DPB01, PPB01 Note When DPB01 or PPB01 is used with phase indicator lamps (see examples in the following diagrams), the lamp H1 or H2 might be dimly lit when there is a phase loss in L1 or L2. This might happen if the lamps used are the typical low power indicator lamps, and there are no other loads present. This fact can be avoided by using W4 models. Note that the neutral must be always connected to the device.
