SZ-10

Power box SZ-10

The SZ-10 type power supply box is a device with a standard design intended for powering devices in installations built in underground workings of non-methane mines and in installations on the surface. The device allows for powering up to 3 receiving tracks. The SZ-10 device is intended for use in an industrial environment, for power supply from an industrial power supply network.
DESCRIPTION
The basic function of the SZ-10 box is to provide a constant supply voltage intended for cooperating receiving devices. The SZ-10 power supply box can operate as a stand-alone device or as a component of the SGA-16 controller. The device is equipped with two power supplies that allow for powering three independent output paths with a voltage of 24 VDC. The power supply for paths marked as UGS1_24VDC (XZ2; terminals 3,4) and UGS2_24VDC (XZ2; terminals 5,6) can be switched depending on the needs from the controller level (e.g. SGA-16) using the K1, K2 and K3 relays built into the device.
In the event of a mains power failure, the PLC_24VDC output track (XZ2; terminals 1,2) is buffer-powered from the battery built into the device.
FEATURES/TECHNICAL SPECIFICATION
The SZ-10 power box is available in four versions, differing in the supply voltage and current efficiency of the power supplies used.
