60V / 20A SMPS DC Regulated Power Supply with PC Interface (1200W)

About.

The Vartech 6020 SR is a 1200 W single-output SMPS power supply rated 0–60 V / 0–20 A with PC interface. Higher current than the 6010 SR for heavier loads at the 60 V range - suitable for 48 V battery packs, EV charger testing and industrial burn-in applications. Features PWM control, auto CV/CC, adjustable OVP/OCP/OPP, encoder controls, preset V & I, Output On/Off, 4-digit LED displays and USB/RS232/RS485 with ModBus-RTU.

• 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: USB standard (RS232 / RS485 optional); ModBus-RTU protocol
• Intelligent temperature-controlled cooling fan
• Low ripple & noise (≤ 0.5% FS rms)
