Product Description
Product Description
eTM-K3030SPL programmable bench power
Use continuously adjustable 0–30V output and a 0–30A 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. 5-digit color screen readouts keep the operating values visible at the bench.
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.

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.
Load-side sensing and cooling
Front-panel SENSE connections support voltage sensing at the load where output-lead resistance causes voltage drop. Use current-rated power leads and keep the rear fan path clear for cooling.
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-K3030SPL
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 5-digit color screen 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 original configuration list also includes an aviation connector and external trigger interface. The listed AC input is 220V. Order the model online; for a different interface configuration, contact us before ordering.
eTM-K3030SPL FAQs
Can this model run a sequence of voltage and current settings?
Yes. Window List supports sequence testing and storage/recall of 100 voltage/current settings. Select the trigger source and operating conditions to match the test procedure.
Does eTM-K3030SPL support SCPI or Modbus?
Both protocols are supported. Match your test controller to the fitted communication interface; RS232 is the listed default, with RS485 and USB configurations also available.
What display resolution does this model provide?
eTM-K3030SPL has a 5-digit color screen with 1mV voltage and 1mA current resolution. Voltage setting accuracy is ±(0.03% of reading + 10mV), and current setting accuracy is ±(0.03% of reading + 10mA), at 25±5°C.
Does the power supply have low ripple and noise?
Yes. Low-noise, low-ripple output is part of the switching supply design. For tests with a specified ripple limit, match the measurement conditions and bandwidth to the requirement.
Which trigger sources can I use?
The control functions support command, level, pulse and external trigger sources, with selectable trigger modes. Match the fitted external connection to your fixture when ordering.
What should I check before ordering online?
Check the voltage/current range, AC input, interface, trigger requirements and output wiring. Order the listed configuration online, or contact us for a specific interface or system requirement.
