Features

Electronic Reversing-Load Relay

ELR W 3/9...

ELR W 3/9... electronic reversing-load relays are the

practical and user-friendly further development of

electronic load relays for 3-phase networks.

The ELR W 3/9... is the fully electronic alternative to

mechanical contactors. It features a compact design

and low control power. A further advantage is the high-

quality, safe screw connection technology.

These components feature high switching

frequencies, virtually unlimited service life, no spark

interference, and completely silent switching at zero

voltage crossing. The compact, DIN rail-mountable

modules meet all the requirements of an electronic

reversing contactor circuit that has been designed

specifically for industrial applications. Both the

interlocking of control inputs and the complete wiring

of the load contacts are incorporated in the device.

Costly locking switches and contact wiring are thus a

thing of the past.

In accordance with DIN VDE 0110 and

DIN VDE 0636, a conductor cross section

of 1.5 mm²(16 AWG), which must be

fitted with one fuse each (10 A slow-blow

as mains protection), is required to

connect the electronic load relay to the

3-phase network.

Cabling has been reduced to an absolute minimum.

Only the following must be applied:

–

Control voltage, supply voltage

input and output

–

3-phase load

The status is clearly indicated by separate LEDs for

"right rotation", "left rotation", "operating voltage" or

"impermissible control".

A short circuit between two phases at the moment of

switching is prevented by the integrated delay

between the control pulse and the load control.

RCV protective circuits on the output side reduce

voltage peaks that occur in the load circuit to a safe

level and prevent damage to the output electronics.
