产品简介
RE20-38-L(200V)-UL 是松田精密（Matsusada Precision）RE 系列的一款直流电源，最大输出电压 20V，最大输出电流 38A，最大输出功率 760W。
With minimal heat dissipation and a significantly reduced footprint compared to conventional linear power supplies, the RE series enables high-density rack mounting. Its high efficiency reduces operating costs and contributes to a more sustainable working environment. Standard features include extensive remote control and monitoring functions. With an optional digital interface, these units integrate seamlessly into automated systems. Choose from over 140 models with outputs ranging from 10 V to 650 V and 0.75 kW to 15 kW. Power output is expandable up to 60 kW using the master-slave parallel operation feature. (UL Certified models available)

To use the optical interface, you need to prepare an optical interface adapter separately. For details, click here.
功能特性
• Remote control connector (TB1)：Note: The signal common of TB1 is internally connected to the negative output terminal. To prevent ground loops or short circuits, ensure that the external control signal connected to TB1 is electrically floating (isolated from the ground). REMOTE/LOCAL change As for the output voltage control, output current control, and overvoltage protection, the remote/local mode can be individually switched b
• Function setting switch (SW1)：Output voltage control 0 to 10 V Local ⇔ 0 to 10 kΩ approx. Output current control 0 to 10 V Local ⇔ 0 to 10 kΩ approx. Overtemperature protection Manual reset ⇔ Auto reset Output state auto-recovery prevention (former: power failure protection) ON ⇔ OFF (ON/OFF by AC)
• Remote sensing：Compensates for voltage drops (Vo-VL) caused by wire resistance (R) or contact resistance to ensure stable output. (Compensation range: Max 0.5 V)
• Output terminal：The form differs depending on the MODEL. Please check which form is in dimension. * The protective cover for terminal board models features two 8 mm diameter holes for cabling as standard. Covers with larger diameter holes are available upon request. Please contact us for details.
