200V / 10A SMPS DC Regulated Power Supply with RS232 Interface (2000W)

About.

The Vartech 20010 SR is a 2000 W single-output SMPS power supply rated 0–200 V / 0–10 A with RS232 PC interface (ModBus-RTU). The highest-voltage standard SR model, it covers testing of high-voltage motor drives, inverter DC bus simulation, and capacitor formation. Features advanced PWM control, auto CV/CC, adjustable OVP/OCP/OPP, encoder controls, preset V & I, Output On/Off and 4-digit LED displays.

• Advanced PWM (SMPS) control technology - compact and light weight
• Auto CV/CC switch with Coarse & Fine encoder control for V and I
• Pre-setting of voltage & current with Output ON/OFF switch
• OVP (adjustable, ≤110% FS), OCP (≤110% FS), OPP (≤100% FS), OTP protections
• 4-digit LED displays for voltage and current (set + readback)
• PC interface: RS232 (standard for this model); ModBus-RTU protocol
• Intelligent temperature-controlled cooling fan
• Low ripple & noise (≤ 0.5% FS rms)
