BX‑COV013 Series is a high‑power wiring‑type intelligent electronic converter designed for home and light commercial use. It provides stable power switching, over/under‑voltage protection, and overload protection to keep your electrical equipment safe in unstable power environments.
Product Overview
- COV013‑3L: 3‑channel power input (L1 > L2 > L3)
- COV013‑4L: 4‑channel power input (L1 > L2 > L3 > L4)

Core Functions
1. Over & Under Voltage Protection
2. Overload Protection
3. Automatic Power Source Switching
4. Generator Auxiliary Switch
5. Voice & Visual Alerts
Voice reminders during delay, over/under‑voltage, and overload. Digital tube displays real‑time voltage and current. LED indicators clearly show which channel is supplying power.

Product Advantages
- High‑quality phosphorus copper components provide excellent conductivity, corrosion resistance and long service life.
- PC flame‑retardant shell meets UL94 safety standards.
- Modular design for easy wall mounting and wiring.
- Wide operating range: -10℃ to 55℃, humidity ≤90%, altitude ≤2000m.
- Supports wiring up to 10mm² for stable and safe connection.
Technical Specifications
Both COV013‑3L and COV013‑4L run at rated voltage 220VAC 50Hz, with under‑voltage protection at 120VAC and over‑voltage protection at 260VAC. Delay time is fixed at 7 seconds. They share the same working environment range, product dimensions of 200×130×36mm and PC flame‑retardant housing. The only difference is the number of input channels: 3 channels for 3L and 4 channels for 4L.
