Racklight, power conditioner, LED voltmeter and voltage peak/transient line filter up to 10A, 2-way LED lighting can be dimmed and pulled out. Rear BNC connector with switch for optional gooseneck lamp (12 V/0.5 A). 10 x rear and 1 x front IEC 230 connectors. 19"/1U, 6kg. Installation depth: 26.7cm. LiFT (Linear Filtering Technology), SMP (Series Mode Protection), EVS (Automatic Extreme Voltage Shutdown) The PL -PLUS CE has Smooth Track LED rack lamps that emit almost no heat and have an extremely long lifespan. With a dimmer control for the rack lamps, the user can adjust the brightness (by turning clockwise/counterclockwise) or switch the lamps on and off (by pushing the button in). A BNC socket on the back takes each (12VAC 0.5 A) gooseneck lamp for rear rack lighting. The PL -PLUS CE also has a three-color LED AC voltage meter that displays the input voltage in 2-volt increments. The accuracy of the voltmeter is ±2.0 volts. It provides information the user whether the voltage is in or outside a safe range from a distance that is normally too great to read the displayed voltage.
