eTM-K3020SPV 30V 20A Programmable DC Power Supply

eTM-K3020SPV programmable bench power

Use continuously adjustable 0–30V output and a 0–20A current setting for development, functional checks and repeatable production tests. The switching design combines low-ripple output with automatic constant-voltage and constant-current operation. 6-digit display readouts keep the operating values visible at the bench.

Rated continuous output is 600W, including simultaneous operation at 30V and 20A.

Repeat test settings with Window List

Store and recall up to 100 sets of voltage and current data. Window List sequence testing reduces repeated manual entry when a test calls for several supply conditions. Select the power-up mode and trigger source to fit the test fixture, from software commands to level, pulse or external triggering.

eTM-K3020SPV specifications

Remote control and fixture integration

Connect the power supply to test software using its supported communication configuration. Modbus and SCPI support allows supply settings and control to be integrated into a repeatable test procedure. Front/rear communication arrangements offer connection choices for bench development and installed fixtures.

RS232 is the listed default communication configuration; RS485 and USB configurations are also available. Ask for the required interface when ordering a system-specific configuration. Contact us for Ethernet requirements. External trigger support and selectable trigger modes allow operation to be coordinated with the fixture.

Readouts, calibration and protection

Select power or load-resistance display where useful, including low-resistance measurement. VSelf voltage auto-calibration helps reduce deviation from the voltage setting. Low ripple and noise support DC tests where supply disturbances matter; the selectable buzzer can be set to suit the workspace.

Protection functions include overvoltage, overcurrent, overpower, overtemperature and short-circuit protection. The original specification table also lists overload and reverse-polarity protection. Keep the load and wiring within the operating limits and maintain clearance for cooling.

Applications for eTM-K3020SPV

DC converters and equipment development

Test DC-powered boards and converter inputs at different supply voltages up to 30V. Store recurring setpoints and apply the same conditions when comparing prototypes or checking production units.

Repeated production checks

Recall the same voltage/current settings for successive units, then use command or external triggering to coordinate power with the test. Stored sequences help maintain consistent supply conditions across a batch.

Computer-connected R&D benches

Use Modbus or SCPI with the selected interface to integrate the supply into a test program. Choose the 6-digit display version when its 1mV voltage and 1mA current resolution match the adjustments and readouts required by your test.

Choose the configuration for your test

Match the maximum test voltage, operating current and startup demand to the model. Select output leads and terminals for the intended current, then identify the communication interface and trigger arrangement needed by the test controller.

Supplied accessories include a power cord, compliance certificate, software disc, wiring terminals and RNB5.5-8 terminals. The listed AC input is 220V. Order the model online; for a different interface configuration, contact us before ordering.
