KGS-A70 Industrial 380V / 220V Wireless Remote Control Switch & Distribution Box Retrofit Module
Industrial-grade 380VAC/220VAC wireless remote control receiver switch module engineered for motor starter panels, pumps, and machinery distribution boxes. Features long-range RF reception up to 4000m, > -114 dBm superheterodyne sensitivity, pure copper transformer, dual-control retention for existing push buttons, and intelligent code learning.
ProEngiTools / Industrial Control Engineering & Technical Overview
The KGS-A70 Series is an industrial-grade high-voltage wireless remote control module designed specifically for retrofit and new installations in 380VAC 3-phase and 220VAC single-phase power distribution boxes, motor control centers (MCC), and pump starter panels. By interfacing directly with the coil circuit of magnetic AC contactors (380V or 220V coil), the KGS-A70 allows operators to wirelessly start and stop heavy-duty industrial machinery, agricultural irrigation pumps, winches, exhaust fans, and conveyor systems from distances of up to 1000m to 4000m line-of-sight.
A standout engineering feature of the KGS-A70 is its seamless dual-control compatibility. Installers can wire the receiver in parallel/series with existing manual start and stop push buttons, preserving local manual control at the distribution panel while simultaneously enabling flexible long-range RF remote operation. This ensures that operational continuity is never compromised, even if a handheld remote is misplaced or undergoing battery replacement.
Built with industrial reliability at its core, the KGS-A70 features a dedicated step-down transformer wound with 100% pure copper wire for stable internal power delivery, immune to high-voltage grid fluctuations. The RF receiver incorporates a high-sensitivity superheterodyne circuit exceeding -114 dBm, offering superior wall-penetration and robust resistance against electromagnetic interference commonly generated by nearby VFDs, transformers, and heavy electric motors.
The module employs an intelligent learning-type microchip for wireless pairing and clearing. Users can easily pair multiple handheld transmitters to a single receiver or replace lost remotes on-site with a simple one-touch code-learning button, eliminating the need to replace entire control units. Housed in a flame-retardant industrial enclosure with secure barrier terminal blocks, the KGS-A70 delivers dependable, fail-safe wireless modernization for factory machinery, construction sites, and remote pumping facilities.
Key Engineering Highlights:
- Universal 380VAC (or 220VAC optional) Industrial Supply: Direct power connection without needing external DC power bricks or fragile switching adapters.
- Dual-Control Architecture: Retains original manual start/stop push buttons on the panel while adding wireless remote operation.
- Contactor Coil Pilot Interfacing: Heavy-duty 10A dry-contact relay terminals (NO, COM, NC) designed to safely switch AC contactor holding coils.
- Ultra-Long RF Transmission Range: 1000m to 4000m theoretical range with high wall-penetration capability (10% to 50% effective range in complex industrial environments).
- High-Sensitivity Superheterodyne Receiver: Sensitivity exceeding -114 dBm operating at 315 MHz for rock-solid signal reception and noise immunity.
- 100% Pure Copper Transformer: Heavy-duty magnetic step-down core provides ultra-stable continuous operation and high surge withstand.
- Intelligent Learning-Type Code Matching: One-key pairing and clearing; easily add or replace remotes without replacing the receiver.
- Compact Panel-Mount Enclosure: 90 mm x 55 mm footprint fits easily into standard distribution enclosures, starter boxes, and DIN rail cabinets.
- Multi-Transmitter Scalability: Supports 1-to-many and multi-channel configurations for centralized control across workshops.
- Industrial Safety Warning Compliant: Requires qualified electrical installation following wiring diagrams for safe contactor coil driving.
