Identification

TECHNICAL DATA

The 460 is a power thyristor unit designed to control an industral single-phase load with a high current requirement at start-up using thyristors.

!

Attention !

It is the user's responsibility to ensure that the nominal values of the thyristor unit are compatible with the conditions of installation and operation before commissioning the thyristor unit.

The following can be reconfigured by the user:

• Phase angle

• Single firing (burst firing with a firing or non-firing cycle)

• Fast cycle

(typical modulation time at 50 % power : 0.8 s)

• Slow cycle

(typical modulation time at 50 % power : 8 s)

• Fast cycle with adjustable soft start between

0 and 250 ms (with or without soft end)

• Slow cycle with adjustable soft start between

0 and 250 ms (with or without soft end)

For inductive loads the delayed firing of the first alternation of the burst mode firing (without soft operation)

eliminates transient currents

Using external switch or external voltage on the control terminal block.

Response time: enable 2 s; inhibition < 25 ms

Connector for diagnostic unit used to adjust and control the thyristor unit using 20 test signals

Squared load current or squared voltage control.

Supply variation compensation.

Shielded cable connected to ground at both extremities.
