Electronic loads
Sinking from 150 W to 60 kW a unit, regenerative and conventional.
A load is the cheapest part of a test bench and the one that decides its running cost. Conventional loads turn everything they absorb into heat, which on a long soak becomes a cooling problem and an electricity bill. Regenerative loads return it to the supply. At British commercial electricity prices the difference stops being an accounting detail somewhere around a continuous 10 kW.
Lines held by another British distributor
Intepro is the North American distributor for these manufacturers, not the British one. We build test systems around their equipment; for the instruments themselves, go to the firm that holds the line here.

AN236 high-power DC electronic load
Supplied and integrated2 kW – 60 kW per unit · 0–150 V, 0–600 V or 0–1200 V by class · 0–80 A to 0–2400 A · 54 models
A high-power DC load family spanning three voltage classes and a very wide current range.
Fifty-four models is the point: load selection is normally a compromise between the voltage you need and the current you need, and a range this granular is how you avoid buying twice the load to get the right corner of the envelope.
EL97xx series electronic loads
Intepro own design150 W – 6000 W and above · 0–500 V sink rating
Intepro's own programmable electronic load range, from small bench units upwards.
The workhorse for power supply verification and battery discharge characterisation, and the load most often built into the racks in the test-systems category.
ELR 9000 regenerative DC load
Integrated, not supplied here3.5 kW – 10.5 kW per 3U chassis · to 1500 V · to 510 A per chassis · 14 models
A regenerative DC load that returns absorbed energy to the mains rather than dissipating it.
Named here because regeneration is a recurring argument in this catalogue and this is a well-known instance of it. Intepro integrates loads of this class into systems; the British channel for the instrument is elsewhere.
Not supplied by Intepro in the UK
EA Elektro-Automatik hardware is held in Britain by Caltest Instruments. Intepro UK designs and builds test systems around this equipment; for the instrument itself, go to them. We would rather tell you that than take an enquiry we cannot properly serve.
