The OWON PSL3258-60 is an 8-channel programmable source/load battery simulator housed in a standard 19-inch 2U chassis. It provides 480W of total output power, with up to 60W per channel, and supports 0–21V and 0–5A output per channel. The system combines a programmable power supply with an electronic load supporting constant power (CP), constant current (CC), constant voltage (CV), and constant resistance (CR) modes. High-resolution source settings and readback measurements enable precise testing, while the built-in DVM interface provides remote voltage measurement. Standard LAN communication supports TCP/IP control, with Type-C, RS232, and RS485 available as optional interfaces. Each channel incorporates independent intelligent fan cooling, while OVP and OCP protections improve operating safety.
