Instek PSP-603 Programmable Switching DC Power Supply

The Instek PSP-603 is a 200W programmable switching DC power supply engineered for laboratory, educational, and industrial test environments. This single-output instrument delivers 0V to 60V at 0A to 3.5A with full remote control via RS-232C interface. A backlit LCD display provides real-time monitoring of voltage, current, and power parameters, while integrated protection circuits guard against overvoltage, overcurrent, overpower, and thermal faults. The bench-top unit operates from 115VAC or 230VAC (50/60Hz) and incorporates 3-step fan speed control for thermal management.
