The "EC" suffix indicates an Electronic Control panel. Here is how to set it up via the front buttons:
Terminal connections (typical):
Over-voltage (230V–300V), Under-voltage (140V–210V), Over-current (1–63A). tomzn tovpd1-60-ec manual
The device trips when line voltage exceeds the set threshold.
Wait for 10 seconds without pressing any buttons. The device will automatically save your changes and return to the home display screen. Parameter Reference Table Adjustable Range Factory Default P1 Over-voltage Protection Threshold 230V – 300V P2 Over-voltage Recovery Voltage 225V – 295V P3 Under-voltage Protection Threshold 140V – 210V P4 Under-voltage Recovery Voltage 145V – 215V P5 Over-current Protection Threshold 1A – 63A P6 Power Recovery Delay Time 1s – 500s 5. Sequence of Operation The "EC" suffix indicates an Electronic Control panel
Includes lightning protection and heat dissipation capabilities up to 105℃.
The is a multifunctional, adjustable protective device. It combines an over-voltage protector, under-voltage protector, and over-current protector into a single compact DIN-rail unit. It is widely used in residential and commercial electrical panels to safeguard sensitive appliances from volatile power fluctuations. Wait for 10 seconds without pressing any buttons
| Model | Key Difference | |-------|----------------| | | Primarily voltage and current protection (similar functions, may have different display layout) | | TOVPD1‑63‑EC | Essentially the same device, often listed as a 63 A variant | | TOVPD1‑II | Over‑current only (no voltage protection) | | TOVPD1‑SKW | Includes Wi‑Fi control via Tuya Smart app (available as a UK or Thai socket) |
This unit is great for protecting refrigerators and AC units. Remember to set the Delay Time (d-t) to at least 3 minutes (180 seconds) for AC compressors to allow pressure to equalize.
