MTP-200 series two-way programmable DC power supply

The MTP-200 series consists of seven complete models (MTP-201 to MTP-207), all equipped with two fully independent, electrically isolated output channels. The voltage coverage ranges from 0~15V up to 0~150V, while matching current ranges from 0~6A to 0~60A, with single-channel rated power between 600W and 900W. This switching-type programmable power supply features unified 1mV voltage and 1mA setting/readback resolution. It supports dual operation modes via numeric keypad and adjustment knob, built-in List sequence programming, and storage for 9 groups of user-defined V/A parameters. Standard SENSE remote voltage compensation eliminates cable line loss. Standard RS232 communication port is compatible with SCPI and Modbus protocols; USB, RS485 and LAN interfaces are factory pre-install optional accessories. Complete OVP/OCP/OTP multi-layer safety protection and intelligent temperature-controlled cooling fan are integrated. The 19-inch 2U rack-mount cabinet weighs 9.5kg, backed by a 3-year official warranty for automated ATE systems, multi-device synchronous testing and laboratory research.

The MTP-200 series adopts switching power conversion architecture and standard 19-inch 2U rack-mount cabinet with unified dimensions of 482×100×372mm and net weight of 9.5kg, compatible with industrial test racks and desktop bench placement. It supports universal AC 220V±10% single-phase input, stable operation under 0~40℃ and ≤85% non-condensing relative humidity, and storage temperature range of -15℃ to 70℃. Each unit has two completely separate output channels with full electrical isolation between them, enabling simultaneous power supply for two independent test objects without signal crosstalk interference.

In terms of output stability and measurement precision, all models share uniform 1mV voltage and 1mA current setting & readback resolution. Under standard 25℃±5℃ test environment, voltage setting accuracy ≤0.1%+10mV and current setting accuracy ≤0.3%+10mV. Load regulation and line regulation indicators differ by model based on voltage and current specifications; voltage ripple is controlled within 10~15mVrms to provide steady DC output for multi-channel component testing. The temperature coefficient is calibrated for long-term continuous operation without obvious parameter drift during aging cycles.

For front-panel interactive operation, dual parameter input methods are provided: direct digital entry via numeric keypad, and fine tuning through rotary adjustment knob. The instrument supports two core programmable test functions: editable List sequence output for unattended multi-condition cyclic testing, and storage & one-click recall of up to 9 groups of frequently used voltage/current parameter sets to boost repeated test efficiency. Dedicated SENSE remote compensation terminals are reserved on the rear panel to offset voltage drop on long output wires, ensuring precise voltage delivery at DUT terminals even with extended wiring distances.

Comprehensive safety protection system includes OVP overvoltage protection, OCP overcurrent protection and OTP overtemperature protection. The power supply automatically cuts off output once voltage, current or temperature exceeds preset safe thresholds to protect both the instrument and tested samples. An intelligent temperature-sensing fan dynamically adjusts rotation speed according to internal heat load, running silently under light load and accelerating heat dissipation under full 900W single-channel output to balance noise and cooling performance.

For automated test system integration, RS232 communication interface comes as standard hardware, fully supporting SCPI and Modbus remote control command sets for upper computer parameter configuration, real-time data reading and automatic test flow execution. USB, RS485 and LAN communication interfaces are optional factory pre-installed accessories and cannot be retrofitted by users after delivery. Standard delivery accessories include power cable, RS232 cable, two pairs of test leads, SENSE wire and complete user manual; official website provides downloadable product datasheet and programming documents for secondary development.

A1 The MTP-200 series has two fully independent and electrically isolated output channels. The two channels can adjust voltage and current separately without mutual signal interference, supporting synchronous testing of two different test objects at the same time.

A2 It supports List sequence output function for editing multi-step automatic test programs, and can save and quickly recall up to 9 groups of preset voltage and current parameter sets to realize fast switching of test conditions.

A3 The SENSE terminal realizes remote voltage compensation, which eliminates voltage loss on long output test wires and ensures the actual voltage at the tested device terminals is consistent with the set value.

A4 RS232 interface is standard, compatible with SCPI and Modbus remote control protocols. USB, RS485 and LAN interfaces are optional accessories that can only be pre-installed at the factory and cannot be added post-delivery.

A5 The power supply integrates OVP overvoltage protection, OCP overcurrent protection and OTP overtemperature protection. It will automatically cut off output when abnormal operating parameters appear to avoid damage to the instrument and tested samples.
