Compact 800 W Wide-Range DC Power for High-Current Testing
The KIKUSUI PWR801L is a compact programmable CV/CC DC power supply combining a 40 V voltage range, up to 80 A current capability, and 800 W rated output power.
Unlike a conventional fixed-range supply, the PWR801L uses a wide-range power-type operating area that allows different voltage and current combinations within its 800 W output-power rating. This provides greater flexibility when powering devices whose voltage and current requirements vary between test conditions.
40 V / 80 A
High-current L-type output with a maximum rated power of 800 W.
Wide-Range CV/CC
Flexible voltage and current combinations are available within the rated output-power envelope.
64-Step Sequence
Programmable sequence operation supports automated changes in voltage and current settings.
LAN / USB / RS-232C
Standard digital interfaces support remote control and automated test integration.
External analog control, variable internal resistance, remote sensing, protection functions, master-slave operation, and synchronized control further support bench, development, production, and system-level power testing.
40 V / 80 A / 800 W Output
The PWR801L provides up to 40 V or 80 A within an 800 W maximum output-power envelope. Maximum voltage and maximum current cannot be delivered simultaneously when the resulting power exceeds 800 W.
Wide-Range CV/CC Operation
Constant-voltage and constant-current operation combine with the PWR-01 wide operating area to support a broader range of load conditions than a conventional fixed-range DC supply of the same power rating.
Programmable Sequence Function
One sequence program with up to 64 steps can automate voltage and current changes. Once programmed by communication commands, the stored sequence can also be executed without a continuously connected PC.
LAN, USB, and RS-232C Standard
LXI-compatible LAN, USB, and RS-232C communication are standard for remote programming, monitoring, and automated test integration.
External Analog Control
Output voltage and current can be controlled through external analog signals or resistance. External contacts also support output ON/OFF, shutdown, and alarm-clear control.
Variable Internal Resistance
In CV mode, the programmable internal-resistance function can simulate voltage drop associated with internal resistance in rechargeable batteries, solar cells, fuel cells, and similar sources.
Remote Sensing
Remote sensing compensates for voltage drop in high-current load wiring, with up to 1.5 V compensation per line for the PWR801L.
Comprehensive Protection
Protection functions include OVP, OCP, front-terminal overcurrent, overheat, sensing-error, low-AC-input, communication-watchdog, shutdown, and parallel-operation protection.

Wide-Range 800 W Operating Area
The PWR801L combines a 40 V maximum rated voltage and an 80 A maximum rated current within an 800 W maximum output-power envelope.
Voltage and current can therefore be combined over a broad operating region without requiring separate supplies for different voltage/current conditions. The maximum voltage and maximum current ratings should not be interpreted as a simultaneous 40 V × 80 A output condition.
40 V Maximum
Rated maximum output voltage for the PWR801L.
80 A Maximum
Rated maximum output current for the PWR801L.
800 W Limit
Voltage/current combinations remain within the rated output-power boundary.
CV / CC
Automatic constant-voltage or constant-current regulation according to the connected load and settings.
