To ensure long-term reliability, every SC-120 UPS Charger undergoes a 100% full load burn-in test before leaving the factory, verifying performance under maximum stress. It also includes a 2-year warranty—a testament to LEYU’s commitment to quality—making it a cost-effective choice for businesses prioritizing power continuity and low maintenance.

Features

Universal Input & Global Compatibility

The SC-120 UPS Charger eliminates the need for voltage adapters with its 90~264VAC/127~370VDC input range, supporting both AC and DC input sources. This flexibility makes it ideal for multi-site operations with varying power infrastructure, such as international manufacturing facilities or remote renewable energy projects. Its ability to handle voltage fluctuations (common in industrial settings) ensures consistent performance without manual adjustments.

Comprehensive Protection Mechanisms

Safety is central to the SC-120’s design, with a suite of protections to safeguard the charger, connected batteries, and critical equipment:

Short circuit protection: Immediately isolates the circuit to prevent component damage.

Overload protection: Triggers at 110%~150% of rated output power (operating in “hiccup mode” for AC charging) and auto-recovers once the fault is resolved.

Over voltage protection: Shuts down temporarily if output voltage exceeds safe limits, preventing battery or device damage.

Battery polarity protection: Uses a high-quality fuse to block reverse current, avoiding irreversible harm to batteries.

Low-voltage battery protection: Cuts off output when battery voltage drops to 9.5~11V (for 12V systems) or 20~22V (for 24V systems), preventing deep discharge and extending battery lifespan.

Energy Efficiency & Silent Operation

The SC-120 prioritizes energy savings with a no-load power consumption of <1W—a critical advantage for 24/7 operations aiming to reduce utility costs. It uses free air convection cooling instead of fans, eliminating noise pollution (ideal for quiet environments like labs or control rooms) and reducing maintenance needs (no fan cleaning or replacement).

Intelligent UPS Charging Technology

At its core, the SC-120 UPS Charger features advanced floating charge technology that maintains batteries at >90% saturation efficiency while automatically stopping charging once full—preventing overcharging, a leading cause of battery degradation. It also supports AC/battery auto-switching with zero switch time, ensuring critical equipment (e.g., PLCs, CCTV) never loses power during outages. For emergencies, it includes a cold-start function: when AC input is unavailable, the charger can use battery power to boot up, meeting urgent power needs.

Compact Design & Easy Installation

With dimensions of 1599738mm (LWH) and a weight of 0.56kg, the SC-120 fits into space-constrained enclosures. It is explicitly designed for installation in both metallic and non-metallic system enclosures, adapting to diverse industrial setups. A built-in LED power indicator provides instant visual feedback on operational status, simplifying troubleshooting and routine checks.

Regulatory Compliance

The SC-120 UPS Charger meets global safety and electromagnetic compatibility (EMC) standards, including UL60950-1 (safety) and EN55022 Class B (EMC). This compliance ensures it can be deployed in regulated industries like healthcare (low-risk devices) and telecommunications, where strict standards apply. It also has a leakage current of <1mA/240VAC and withstands voltages of 3KVAC (I/P-O/P), 1.5KVAC (I/P-FG), and 0.5KVAC (O/P-FG) for enhanced safety.

Applications

Industrial Automation Systems

Industrial automation relies on uninterrupted power for PLCs, sensors, and motor drives—even brief outages can cause costly production downtime. The SC-120 UPS Charger’s zero switch time and wide input range make it ideal for this sector: it stabilizes power during voltage spikes or outages, ensuring automation processes run smoothly. Its compact size also fits into control panels alongside other equipment.

Security & CCTV Surveillance

CCTV systems require 24/7 power to maintain continuous monitoring and footage recording. The SC-120’s low no-load power consumption (<1W) reduces long-term energy costs, while its intelligent battery protection (overcharge, low-voltage) ensures backup batteries remain functional for extended outages. Its low ripple & noise (120mVp-p for SC-120-12, 180mVp-p for SC-120-24) also prevents interference with camera signals, preserving video quality.

Telecommunication Equipment

Routers, switches, and small cell towers depend on stable power to maintain connectivity. The SC-120’s 120W rated power and -10°C~+60°C operating temperature range make it suitable for indoor and outdoor telecom sites (e.g., remote cell towers). Its comprehensive protection shields sensitive telecom gear from power surges, while its AC/battery auto-switching ensures calls and data transmission never drop.

Medical Devices (Low-Risk Applications)

For low-risk medical equipment—such as patient monitors, portable diagnostic tools, or laboratory analyzers—the SC-120’s stable output (low ripple & noise) and UL60950-1 compliance meet strict industry regulations. It provides reliable backup power during hospital power outages, ensuring critical monitoring tasks continue without interruption.

Renewable Energy Systems

In solar or wind energy setups, the SC-120 acts as a complementary charging solution for backup batteries. Its floating charge technology maintains battery health, ensuring stored energy is available when renewable sources (e.g., solar panels) are inactive (nighttime, cloudy days). It pairs seamlessly with MPPT/PWM solar controllers, enhancing the reliability of off-grid or hybrid energy systems.

Emergency Backup Systems

For emergency equipment like fire alarms, emergency lighting, or public address systems, the SC-120 UPS Charger’s cold-start function and long battery life protection are critical. It ensures these systems activate immediately during power failures, complying with safety regulations and protecting lives.
