INV
increases. This system is for relatively small capacities.
Being a totally enclosed type, this system is the most
appropriate for hostile environment having dust, dirt, oil
mist, etc. The enclosure size increases depending on
INV
the inverter capacity.
This system has restrictions on the heat sink mounting

capacities.
This system is for general indoor installation. This is
appropriate for enclosure downsizing and cost
