Current sinking up to 100% of rated current requires one power dissipator for 1 kW models, and two power dissipators for 2 kW models. 2
kW models with one power dissipator can sink 50% of their rated current.
2
Maximum continuous power available is derated at 1% of rating per degree C from 40°C to 55°C
3
From 20 Hz to 300 kHz for rms noise; from 20 Hz to 20 MHz for peak-to-peak noise
4
At 23°C ±5°C after a 30 minute warm-up; measurement NPLC=1; valid for 1 year, see Calibration Interval
5
With resistance programming enabled, the voltage programming offset component increases by a factor of 3.15
6
Load lead drop applies to each load lead
7
Time to recover to within the settling band following a load change from 50% to 100% of full load (10 µs rise time)
