The Smartec assortment now includes ST-PS110BPL-WT universal power supplies in a plastic box with space for a 17 Ah battery
The novelty is protected from overload and short circuit with automatic recovery, while protecting the connected device from a power supply failure. In case of a drop or absence of voltage in the mains, the power supply in a plastic case switches to battery power, while protecting it from deep discharge, from excessive charge or polarity reversal when connected. Other advantages of the model include the presence of LED indicators of the status of lines and batteries, as well as the ability to expand the functionality to increase the capacity of the system.
A convenient design in a box with a place for a battery and a securely fixed door distinguishes the ST-PS110BPL-WT from models with a DIN rail mount. Inside the case, there is space for a battery with a capacity of up to 17 Ah (purchased separately), to which the device automatically switches when the voltage drops in the mains. It should be noted that the power supply is made of plastic, which provides it with a relatively low cost. For clarity and convenience of monitoring both lines and the battery, the novelty is equipped with appropriate LED indicators.
The built-in protection of the power supply case allows you to avoid the breakdown of the power supply in case of overload or short circuit. If the power of the device connected to it exceeds the permissible one, ST-PS110BPL-WT is disconnected from the device, maintaining further operability. Similarly, this power supply in a plastic case reacts to a short circuit. It is important that the power supply also protects the load (connected device) from failure, which can happen in the event of a power supply failure.
The mains voltage stabilization function is also performed by the Smartec power supply. With a rated voltage of 220 V, the real voltage may not correspond to it, with a deviation of up to 10%, both up and down. In both cases, the plastic-encased power supply provides a stable output voltage for the safe operation of the connected equipment.
To provide power to small/medium-sized office access control systems or segments of large access control systems is the task of the ST-PS110BPL-WT power supply. If necessary, this power supply in a plastic case can be equipped with branded additional modules, expanding its functionality with relay outputs for monitoring the status of 220 V line and battery, as well as output channels with individual fuses.
