KSB - Stabilized switching buffer power supplies
The KSB series regulated switching buffer power supplies, designed for DIN rail mounting, are intended for applications requiring uninterrupted power supply. They enable simultaneous powering of connected loads from the AC mains while charging the backup battery. In the event of a mains power failure, the units automatically switch to battery operation.
Built-in short-circuit, overvoltage, and overload protection functions, together with battery protection features, enhance operational reliability and safety.
The power supplies are equipped with natural convection cooling, LED status indicators, and signaling outputs, facilitating integration and monitoring in industrial automation, security, and industrial control systems.
Features:
- simultaneous powering of connected loads and battery charging,
- automatic switchover to battery operation in the event of AC mains failure,
- comprehensive protection system: short-circuit, overload, and overvoltage protection,
- battery protection against deep discharge and reverse polarity connection,
- high operating temperature range – up to 70°C*,
- high efficiency and reliability,
- long service life,
- natural convection cooling (fanless design).
Applications:
- industrial automation,
- security and alarm systems,
- emergency lighting,
- DC UPS systems,
- video surveillance and access control systems.
