The clear LED signaling and the device connection with double terminal block for plus and minus for fast potential
distribution are further advantages of this device series. A third minus terminal block simplifies the grounding on the
secondary side. All power supply units are idle-proof and short-circuit-proof and provide a regulated and adjustable
output voltage.
