Description

CIHLA is High End linear low noise external power supply for Serge synthesizers. Inside of rigid metal enclosure is PCB with electrical components, toroidal transformer, heatsink etc. On one side of enclosure is power inlet for main voltage with power switch and fuse holder. On second side are four output connectors, banana ground connection, GND / LIFT switch and +12V / -12V LED which present output voltages. In normal operation mode when the power switch is ON, LEDs are light on green. LEDs go out when some rail is overload or short. Primary side of PSU contains LC filter, which removes interference from AC mains. Toroidal transformer with metal cover is the key element to minimize electromagnetic interference. CIHLA is made on quality PCB with copper thickness of 70 μm, which ensures reliability of CIHLA and minimal losses on PCB routes. GND / LIFT switch can be used for disconnection (LIFT position) secondary ground potential from primary / enclosure ground potential. This feature can help to solve problems with ground loops when more devices are patched between them and supplied from one or more wall socket (synth, mixer, PC…). In normal conditions without ground loop problems is good to keep switch in GND position.
