eTM-L2501SPD+ 250V 1A Programmable Linear DC Power Supply

eTM-L2501SPD+ programmable linear bench power

Use adjustable 0–250V output and a 0–1A current setting for circuit development, repeatable functional checks and automated test fixtures. The linear design provides low-noise, low-ripple DC output, while the 6-digit LED display keeps the operating values visible at the bench.

Set and repeat your test conditions

Set voltage and current from the keypad or adjustment knob, then enable the output. Automatic CV/CC operation controls the output as the load reaches the selected current limit. Window List supports sequence testing with storage and recall of 100 sets of voltage/current data. Select a power-up mode and trigger source to match the fixture: command, level, pulse or external triggering.

eTM-L2501SPD+ specifications

Low-ripple output and load-side sensing

Low ripple and noise help keep supply disturbances out of DC measurements and functional checks. Front-panel SENSE connections support load-side voltage sensing to compensate for voltage drop in the output leads. Use the output terminals for the load current and connect the sense wiring according to the product manual.

Readouts, calibration and bench controls

Select power or load-resistance display, including low-resistance measurement, to suit the work. VSelf voltage auto-calibration helps reduce deviation from the set voltage. Output on/off control, keypad lock and a selectable buzzer support everyday bench operation. Keep the cooling fan and ventilation openings clear during extended tests.

Remote control and test-system integration

Modbus and SCPI support allows eTM-L2501SPD+ to work with compatible test software. The front/rear communication arrangement provides connection choices for bench development and integrated fixtures. RS232 is the default communication configuration; RS485 and USB configurations are available. Specify the interface required for your controller when ordering, and contact us for Ethernet requirements.

Protection functions

Overvoltage, overcurrent, overpower, overtemperature and short-circuit protection are provided, together with overload and reverse-polarity protection. Use the supply within the specified operating limits. Where the connected device can return energy, include suitable external backfeed protection in the test setup.

Applications for eTM-L2501SPD+

High-voltage DC circuit testing

Sweep DC input conditions within 0–250V for component assemblies, DC input stages and laboratory fixtures rated for the test voltage. Set the current limit before enabling the output and use suitably rated leads and connectors.

Repeated production checks

Recall stored voltage/current conditions for successive units and use the selected trigger source to coordinate power with the fixture. Sequence operation reduces repeated manual entry when each unit must be checked at several supply settings.

Computer-controlled laboratory tests

Use Modbus or SCPI through the chosen communication interface to incorporate the supply into a test procedure. Local readouts and front-panel controls remain useful when setting up the fixture or checking its operation.

Choose your configuration and order

Match the required voltage range, operating current and startup demand to this model. Select the communication connection needed by your controller and account for the required trigger wiring. The AC input supports 110V / 220V selection; set it for the local supply before use.

Supplied accessories include the power cord, compliance certificate, 2.0 and 4.0 wiring terminals, software disc and output clip lead. Order the listed model online. For a specific interface or integration requirement, contact us with the configuration you need.
