eTM-DM-KKK Triple Output DC Power Supply – 3 × 160V 5A

Three adjustable supplies in one bench unit

eTM-DM-KKK combines three adjustable switching power modules in one enclosure. Each channel provides a 0–160V voltage range and 0–5A current setting, with separate channel readouts and output controls. Use one unit to power several DC circuits or test positions without filling the bench with three separate supplies.

Set the voltage, limit the current and control the output

Set voltage and current before enabling the output. Automatic constant-voltage and constant-current operation lets the supply respond as the load reaches the selected current limit. Four-digit LED readouts show voltage, current, output power and equivalent impedance, with CV/CC indicators for the operating mode. Encoder adjustment and output on/off control keep repeated bench operations within reach.

eTM-DM-KKK specifications

Connect to a test controller

The 3-in-1 RS232, RS485 and USB communication configuration supports Modbus RTU control. Select the connection that suits your controller and cabling. Use the matching command/register documentation when setting up automated tests.

Protection and low-ripple DC output

Voltage ripple of ≤20mVrms and current ripple of ≤20mArms support steady DC test conditions. Overvoltage, overcurrent, overpower, overtemperature and short-circuit protection cover the supply’s main fault conditions.

Applications

Multi-rail circuit development

Supply up to three DC circuits from one enclosure. Set each channel for its required operating point within 0–160V and 0–5A, then observe the individual readings while checking circuit behavior.

Production and functional test fixtures

Power multiple test positions or subassemblies from separate channels. Per-channel output controls help operators enable the required circuit while keeping the others off.

Computer-controlled test benches

Connect through the appropriate communication interface and coordinate power application with the test sequence. For loads that can feed energy back into the supply, include suitable external backfeed protection in the test system.

Choose a three-module configuration

eTM-DM-KKK uses three K modules, each rated for the voltage/current range above. For mixed voltage rails, the DM series offers the following module choices:

Order the listed three-channel model online, or use the custom DM configuration for a different module combination. Supplied accessories include a power cord, compliance certificate and three clamp leads. Select the available AC input and communication options before adding to cart.
