Outdoor Weatherproof Enclosures
Padmounted fiberglass enclosure for outdoor installations includes pre-wired ventilating fans and provision for padlocking. Type PE Data Sheet

Primary Disconnect Switch and Fuses
Adds built-in switch, fuses, and terminal blocks to speed installation and provide a single-point on-off converter control. Standard in configuration MA-R

Automatic Controls
Adds built-in fuses, magnetic starter, terminal blocks, and time delay relay to allow converter to be turned on and off by the load controller in unattended applications. Standard in configurations MA-A and DP-A.

Transformers for Special Output Voltages

• Step-Up: Used where supply voltage is 240V, 1-phase but 480V, 3-phase output is required. Connection diagram
• Delta-Wye: To change the converter output from 3-wire delta output to 4-wire wye. Connection diagram
• Buck-Boost: To reduce or increase input voltage by 10-15%. Change 240 V supply to 208 V or vice versa. Connection diagram

Voltage Regulation for CNC Machines
Especially designed for CNC applications and for variable frequency drives. Enables the converter to maintain balanced output voltages over a wide load range.

Lightning Protection
Factory installed lightning and surge protection provides first line protection against incoming line surges. Use this feature in remote areas or high elevations subject to frequent electrical storms or line disturbances.
