Centrally Supplied Locking Systems

In an era where smart buildings, automated logistics, and self-service infrastructure dominate our daily lives, the humble mechanical lock has undergone a radical transformation. Today, centrally supplied locking systems represent the gold standard for organizations seeking reliability, sustainability, and operational efficiency. At the forefront of this evolution stands KERONG, a leading provider with over 24 years of R&D and manufacturing experience in electronic locks and control systems.

Key Advantages Unlike traditional battery-powered smart locks that require periodic battery replacements and ongoing maintenance, centrally supplied (hardwired) locking systems draw power directly from a central power supply unit. This architecture eliminates the single greatest pain point of electronic access control: battery dependency.

1. Cost Efficiency

By eliminating the need for individual control electronics in every lock, centrally supplied systems significantly reduce per-unit hardware costs. The locks themselves can be simpler, more compact electromagnetic or motorized mechanisms.

2. Simplified Maintenance

When a software update, configuration change, or diagnostic check is needed, technicians interact with a single controller rather than servicing dozens or hundreds of independent modules. Troubleshooting becomes faster and more systematic.

3. Unified Power Management

A centralized power supply with battery backup ensures that all locks remain operational during outages. There’s no risk of individual lock batteries dying at unpredictable intervals—a common pain point in decentralized systems.

4. Scalable Architecture

While expansion is technically limited by the controller’s port capacity, modern designs support dozens of locks per bus. For standard parcel locker deployments (ranging from 20 to 100+ compartments), this architecture hits the sweet spot of performance and simplicity. KERONG's centrally supplied solutions are engineered for modern lockers, parcel delivery systems, smart offices, healthcare facilities, educational institutions, and leisure centers. Two Core Technologies Powering the Revolution KERONG's centrally supplied portfolio is built around two distinct but complementary locking mechanisms: electronic solenoid locks and electronic motor locks. Each technology is optimized for specific operational demands, giving system integrators and OEMs the flexibility to match the right lock to the right application. Electronic Solenoid Locks: Precision Electromagnetics for Instant Response

Solenoid locks operate on the principle of electromagnetic actuation. When energized, a coil generates a magnetic field that drives a plunger or locking bolt to engage or disengage the mechanism. KERONG's KR-S66 Series Mini Solenoid Locks exemplify the pinnacle of this technology.

Electronic Motor Locks: Intelligent Actuation for Complex Mechanisms

Where solenoid locks rely on electromagnetic force, electronic motor locks utilize precision DC motors to drive the locking mechanism. KERONG's extensive rotary latch portfolio — including the KR-S70, KR-S79, KR-S98, and KR-S99 Series — demonstrates the versatility of motorized locking technology. Motor locks shine in high-traffic, continuous-use environments where durability and operational silence are non-negotiable.

Whether your project calls for the instant electromagnetic solenoid series or the precision motor-driven reliability of KERONG's rotary latch portfolio, KERONG delivers engineered solutions that are built to last, designed to integrate, and backed by decades of proven expertise.
