Dangerous voltages exist this equipment. Observe usual safety precautions when operating, wiring, servicing reduce risk shock injury.
INPUT VOLTAGE
Input circuit configuration automatically selected internal circuitry input voltage ranges. input voltage greater than VDC) applied, voltage doubler configuration input circuit automatically locked will reconnected unless input power interrupted. (Reset time less than seconds).
Although LZS-250 power supplies will reliably operate from input voltages between 85-132 VAC, regulatory agency compliance only applicable line voltages between VAC, frequencies between (Regulatory agency compliance testing process time this writing. Check unit's chassis appropriate agency logo(s) determine whether particular unit agency approved.)
OUTPUT VOLTAGE
This power supply operates constant-voltage source with maximum load ratings listed page load current tries exceed 110% rating, output voltage will begin decrease toward zero, thereby limiting current delivered load. Upon removal overload, normal operation will resume.
When shipped from factory, power supply ready with output voltage nominally 5.0, 12.0 20.0 volts, respectively, models. Jumpers place TB201 local voltage sensing. Where precise regulation required directly load, remote voltage sensing utilized. This achieved utilizing remote sense terminals TB201 connector (see Figs.
shown page LZS-250 power supplies have both maximum current rating maximum output-power rating function ambient temperature). Care should taken limit both output current output power within specified limits. these limitations adhered internal thermal protection circuit shut down power supply's operation. remote voltage sensing, maximum limits output power, given page apply power supply output terminals, remote sensing point.
OVERVOLTAGE PROTECTION CIRCUIT ADJUSTMENT
overvoltage protection circuit provides adjustable means disabling output should exceed predetermined safe value. When shipped from factory, overvoltage level each unit given page different threshold required, adjusted using following method:
Turn Adjust potentiometer fully least turns).
With power supply unloaded, threshold desired. This require remote programming (see Figs.
Slowly turn adjust control while monitoring output voltage. Stop turning control immediately When FAULT indicator lights, indicating shutdown. this point, threshold desired value.
