Hp Capacity** (air-cooled eddy-current modules):

**Actual air-cooled eddy-current capacities are test speed and rotor-temperature dependent. Initial cold torque and Hp limits are approximately twice their warm ones. (Hp ratings shown below taken after running 1+ minutes, at full load, in a room-temperature environment.) Continuous ratings are approximately 50% of warm values. See online load charts for curves.
150 modules ≈ 150 Hp (warm – per module)
1000 modules ≈ 1,000 Hp (warm – per pair of modules)
1500 modules ≈ 1,500 Hp (warm – per pair of modules)
2000 modules ≈ 1,000 Hp (warm – per pair of modules)
3000 modules ≈ 1,500 Hp (warm – per pair of modules)
4000 modules ≈ 4,000 Hp (quad-absorbers)
6000 modules ≈ 6,000 Hp (quad-absorbers)
4000-HT modules ≈ 4,000 Hp or ≈ 50,000 ft-lbs (octo-absorbers)
6000-HP modules ≈ 6,000 Hp or ≈ 10,000 ft-lbs (octo-absorbers)
6000-HT modules ≈ 6,000 Hp or ≈ 100,000 ft-lbs (dodeca-absorbers)
10000-HP modules ≈ 10,000 Hp or ≈ 12,000 ft-lbs (octo-absorbers)

Hp Capacity (AC motoring absorber modules):

400 modules ≈ 400 Hp (per pair of modules)
800 modules ≈ 800 Hp (per pair of modules)

Hp Capacity** (water-brake modules):

**Approximate; water-brake capacities are test speed dependent.
1800 modules ≈ 1,800 Hp (full brake – per pair of modules)
