The Cressall AC100 load bank is designed for on-site testing of three-phase AC generators and power supplies at 400/230V at continuous powers adjustable up to 100kW.

Capacity
400V 3 phase, 50/60Hz: 100kW in 1.25kW steps
230V 1 phase 50/60Hz: 33kW in 400W steps
Other AC voltages
Lower AC test voltages can be applied; the maximum power is reduced accordingly.
For example: 220V 3 phase, 50/60Hz: 28kW in 350W steps
110V 1 phase, 50/60Hz: 7kW in 85W steps

Resistor Elements
Metal sheathed wire elements manufactured from high-grade nickel/chrome resistance wire in magnesium oxide insulated stainless steel tubes and 600V primary insulation.

Capacity
30kW at 400V, 3 phase, in sections of 1, 2 x 2, 5 and 2 x 10kW
15kW at 230V, 1 phase, in steps of 333W

Test voltages
380/415V, 3 phase 50/60Hz
220/240V, 1 phase 50/60Hz

Controls
Integral control panel with:
1 – 48mm DIN voltmeter 0-500V
3 – 48mm DIN ammeter 0-80A linear
1 – 48mm DIN frequency meter 45-65Hz
2 – single pole MCB’s for short circuit protection
1 – meter fuse

Resistor Elements
Cressall expanded mesh and mica card elements made from with high-grade nickel-chrome stainless steel with 750V insulation.

AC6 Dual Voltage for testing portable generators up to 6kW, 110V and 230V AC

Capacity
0-6kW in 333W switched steps of 333W. 666W, 3 x 1kW and 1 x 2kW, switched in any combination.
At 110V this dual voltage version is limited to 3.5kW by the IEC-60309-2 32A plug connector.

Test voltages
Two switch-selected voltage ranges:
220-240V, 1 phase 50/60Hz
110-120V, 1 phase 50/60Hz

Controls
Integral control panel with removable weatherproof lid with:
1 – 48mm DIN voltmeter 0-300V linear
1 – 48mm DIN ammeter 0-100A linear
1 – 48mm DIN frequency meter 45-65Hz
1 – 3 position rotary switch 110V – OFF – 230V
2 – single pole MCB’s for protection
1 – meter fuse

Resistor Elements
Mica card elements wound with high-grade nickel-chrome stainless steel resistance tape with 600V primary insulation.

Cooling
Fan cooled with a single 170mm fan powered from the test load itself. The fan is mounted on one side of the load bank and blows horizontally through mesh screens on each side.

Input cables and connectors
Two 1.5m flexible input cables complete with colour coded input connectors to IEC-60309-2 are fitted as standard.

Case
All aluminium, finished in red powder coat, with instructions and warning labels. The load bank is fitted with a detachable cover with carrying handle and built-in cable stowage box.
Dimensions: 495 x 220 x 550mm high
Weight: 12kg complete
