• 100 kW at 480V, 3 PH, 60Hz, 5 kW load step (Unit will provide 93.75 kW at 240V, 3 PH, 60Hz, 3.75 kW load step and will de-rate to 70 kW at 208V, 3PH, 60Hz)
• 80 kW at 400V, 3PH, 50Hz, 5 kW load step

Proper cooling is provided by four (4) integral cooling fans. The cooling fans are fuse protected.

An external 120V, 1 Phase, 60 Hz, 5 amp power source is required for the fan and control circuits. This power is derived from the control power receptacle located on the back of the unit.

The standard local mode is manual control via “digital toggle” switches. The local mode features full digital monitoring and individual load steps with LED indications. The integral control panel is provided for load bank operation and includes the necessary controls and status indicators.

The optional remote control mode is via the hand-held touchscreen controller. It features a 4.3″ color touch screen housed in a rugged and easy to grip industrial grade enclosure. Load selection can be the sum of the entire load string (up to 25 load banks) or individual units within that string. Extremely fast and reliable CANbus communication protocol is used in the SIGMA LT for networking. CANbus protocol reduces network sag which is typically found in RS232 network load banks. A USB port is provided for data download and software updates.

The 2705 is constructed using heavy gauge aluminized steel per ASTM A463. It is designed for continuous indoor operation. Two (2) moveable and two (2) fixed casters are provided for easy mobility. Handles are provided for lifting the load bank when it is being transported. All exterior fasteners are stainless steel. The 2705 load banks are listed to UL standard 508A.

The 2705 has a high quality baked polyester powder coated finish with a film thickness of 2.8 +/- 0.4 mils per coat. The standard color is gray (ANSI 61).

Length = 639mm
Width = 413mm

Exhaust temperature sensors are provided to monitor the flow of cooling air. These switches are electrically interlocked with the load application. If the fans are not working properly, the load steps are disabled and an error message is displayed on the load bank and also on the hand-held (if connected).

The load bank also contains fuses for short circuit protection. The control circuit is protected with a 5 amp fuse while the voltage signals to the meter are protected with 1 amp fuses. The load circuit is protected with three main line fuses (one per phase).
