Features And Functions - VOLTCRAFT SPS12/120 Bedienungsanleitung

5. Features and functions

• The high current power supply 12/120 is based on switching power supply technology, which has the advantage of
reducing the weight and size of the device. Switching power supply units use chopped power supplies and return
a broad spectrum of harmonic waves to the mains power line, which may cause interference in other devices. To
suppress these harmonic waves, a PFC (Power Factor Correction) has been installed.
• The direct voltage output is electrically isolated and features a protective function that disconnects it from the
mains voltage.
• The output voltage is preset to 13.8 V and can be reset using the control (4) from 12.6 V to 14.8 V DC. A. Limiting
the current is not possible.
• Two coloured high current terminals with 4 mm measuring jacks on the back of the device are used for the second-
ary DC connection.
• The power supply unit is cooled by two temperature-controlled fans. For this reason, make sure there is adequate
air circulation and ample distance from other objects.
• The power supply unit is equipped with an overload protection switch. This is activated when the maximum permis-
sible current is exceeded due to an overload or short circuit. A red display light indicates an overload. When this
lights up, the consumer and its current consumption must be checked.
