12V 3A UPS Power Supply Unit ZTP1203B with Battery Slot, Dimensions 225×195×75 mm

The 12V 3A UPS Power Supply Unit ZTP1203B with Battery Slot is a compact uninterrupted power supply designed to provide stable 12 V DC output for small security and low-voltage systems. With integrated battery charging and protection circuitry and physical dimensions of 225×195×75 mm, it is intended to maintain continuous operation of devices such as CCTV cameras, access control panels, routers and other equipment that require a reliable backup power source during mains interruptions.

Advantages

This UPS unit combines a regulated 12 V DC output with an internal battery slot and charging management to offer automatic switchover to battery power when mains fail. The charging and protection circuitry prevents overcharge and offers basic short-circuit and overload protection for connected equipment and the battery. Its compact metal enclosure and standard footprint allow installation in small cabinets or on mounting surfaces where space is limited.

Подходит для

• Небольшие системы видеонаблюдения (до суммарной нагрузки 3 A)
• Системы контроля доступа и охранные панели
• Маршрутизаторы, коммутаторы и сетевое оборудование с питанием 12 V
• Промежуточное резервирование питания для бытовой или коммерческой электроники

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 3 A
• Built-in battery slot for a single backup battery (lead-acid / AGM type compatible with 12 V systems)
• Integrated charging circuit with battery protection functions
• Dimensions: 225 × 195 × 75 mm
• Enclosure: compact metal housing suitable for wall or cabinet mounting

How to use

Install the unit on a stable surface or inside an equipment cabinet using appropriate screws or brackets. Connect the mains input following local electrical regulations and then fit a compatible 12 V backup battery into the dedicated slot, observing correct polarity. Connect the 12 V DC outputs to the load devices, ensuring that the total current draw does not exceed 3 A. When mains power is present the unit supplies the load and charges the battery; if mains fails the unit automatically switches to battery power to maintain output voltage.

Usage recommendations

Use a sealed lead-acid or AGM battery sized for the intended runtime and within the unit's mechanical slot dimensions. Verify combined device current consumption to avoid overload and perform periodic battery checks and replacements according to battery manufacturer guidance to ensure reliable backup operation.
