RELIANCE GV3000/SE AC General Purpose and Vector Drive

DESCRIPTION

The variable-voltage, variable-frequency power inverters of the GV3000/SE series are ready for installation and are available in different sizes with output currents in the range 2 to 360 Amps. They are designed to drive induction motors at variable speeds using PWM technology. The protective enclosure contains the Power Module and the Control Unit with the Keypad.

Electrical Description

Three phase input power is applied to terminals L1, L2, and L3 via external standard input fuses or fused isolator. Power is then fed to the precharge circuitry through the optional input filter circuit. This filter keeps conducted emissions in the high frequency range within the limits as per EMC product standards. The current transformer T4 senses ground fault currents (on types 038/043 and 058 - 360). The internal switching power supply develops the isolated DC 24 V control voltage and different supply voltages (DC ±5 to 24V) for the controller operation. An optional, user supplied AC-line input reactor allows the Power Module to be operated on any supply line also with high fault level (refer to chapter 5, Accessories). On types GV3000E-AC003 - 030 and 039/044 the inductance of the optional RFI filter allows connection to supply transformers with a fault level up to 29 kA (e.g. 1000 kVA) after which a choke should be fitted.

When line voltage (or DC-bus voltage on type DC240 and DC360) is applied at the input terminals (external main contactor has picked up), the DC-bus begins charging. The DC-bus voltage increases to a value 1.4 times the no-load three-phase line voltage on types AC003 - 170 resp. to the value of the applied DC-voltage on type DC240 and DC360. Precharge resistors limit the DC-bus capacitors' charging current. When the DC-bus reaches 95% of its rated voltage, the parallel connected precharge contactors close and bypass the resistors.
