Working Principle
The Instant Electric Water Heater Full-Unit Performance Testing Bench operates by supplying controlled water flow at adjustable pressure and temperature. Electrical parameters including voltage, current, and power are monitored synchronously while the system measures outlet temperature stability and flow. The PLC-based industrial computer executes preprogrammed test sequences, records data, evaluates compliance, and generates alarms for nonconforming units. Data is stored and exported via USB for analysis.
