The CRA650LHi uses the same 5kg, 9-inch display chassis as the CRA650LSi and steps the voltage output up to 4×300V, trading two voltage channels for double the compliance margin per channel. Current output is 3×30A at 110W, running on standard AC mains (100–240V) with no battery dependency. The practical case for 300V-class output over 130V-class is straightforward: longer test lead runs, aged or higher-resistance secondary wiring, and relay types that require higher open-circuit voltage to source rated test current reliably. If a 130V-class unit has ever stalled mid-test due to voltage collapse across a long lead run or corroded terminal block, the CRA650LHi's compliance margin directly solves that problem. At 5 kg, it is 3 kg lighter than the 8 kg AC-mains class units that offer equivalent or lower voltage output, making it a practical choice for engineers who move between sites regularly.
