1.Description

The ISP is an amplifier/power supply package, assembled on a single heatsink with a Eurocard size. The rated output is up to 1500W.

The integrated power supply includes a shunt regulator.

The ISP is available in either panel version or rack version with a 32 poles DIN 41612 connector.

*Zero deadband.

*Excellent linearity.

*2 inputs.

*Differential input.

*Motor current monitor.

*Inhibit/fault indication (free contact relay).

*Remote control functions: Inhibit and CW/CCW disable.

*Adjustable compensation.

*Adjustable continuous and peak current limits.

*Dynamic contouring of continuous and peak current limits.

*Input balance (offset) adjustment.

*Operation in two velocity modes (Tacho or armature voltage feedback) or current mode.

*LEDs diagnostics.

*Option - Personality board for ease of replacement: the board includes all the adjusting trimmers.

The following protections cause an inhibit which is either self-restart or latched (for manual reset) selectable by the user:

*Under / over voltage.

*Short circuit: between outputs or each output to ground.

*Low inductance.

*RMS current limit.

*Loss of tacho feedback.

*Over temperature.

*Duty cycle limit of the power supply's shunt regulator.
