Modifications from VVVF to VVVF
Box dimensions: x mm
Box dimensions: x mm
Board dimensions: x mm
Board dimensions: x mm
Modifications:
) IGBT transistors on a heat sink changed to a hybrid IGBT module.
) IGBT IR driver changed to SMD format
) Diode bridge to a different format
) Connectors from the wire to the component side
) Relays from Alcatel to OMRON trade mark (both UL rated).
) Leds from the wire to the component side
) Press buttons changed.
) Microprocessor changed to SMD format.
) New memory with more capacity and with reset and watchdog system incorporated.
