PCX-6220
150A QUASI-CW LASER DIODE DRIVER/PULSED CURRENT SOURCE
Output Current 150A Output Voltage Peak, 1.2kW Average Output Power Pulse Width 50µs 20ms 5KHz Maximum Frequency Maximum Duty Cycle IEEE-488 (GPIB) RS-232 Computer Interfaces
PCX-6220 air-cooled, high power switch-mode pulsed current source designed drive diode lasers, bars arrays. delivers current pulses variable from 150A, pulse widths variable from <50µs 20ms, pulse repetition frequencies variable from single shot 5KHz duty cycles 50%. microprocessor-controlled front-panel RS-232/IEEE-488 interface provide individual control each electronic function, while backlit alphanumeric display provides immediate visual confirmation operating parameters, including output current amplitude, pulse width, repetition frequency, duty cycle, error fault messages. addition stand-alone operation, PCX-6220 externally triggered. output voltage, output current average output power continuously displayed front panel display. Instrumentquality analog current voltage monitors synchronization output also provided real-time monitoring current voltage laser diode. Internal power supplies provide necessary support power driver, allowing operation 90-260VAC, 50-60Hz mains. additional power supply control pulse generator inputs needed, making PCX-6220 complete laser diode driver solution. Connection laser diode made through innovative rear panel, impedance stripline cable, designed preserve
fidelity high-speed, large-amplitude current pulses. operator safety, output connector interlocked, that PCX-6220 disabled when connector removed. PCX-6220 features advanced circuitry protect both diode driver. user-adjustable over-current limit provides fail-safe mechanism prohibit user from setting current amplitude setpoint above user-controlled limit, protecting laser diode from accidental over-drive. over-voltage limit protects diode from erroneous over-voltage conditions, temperature monitor protects driver event overtemperature condition. turn time driver enabled, PCX-6220's output electronically shorted ground, ensuring that current flows through diode. addition, actual current through diode monitored real-time. actual current ever exceeds user-adjustable current setpoint, driver truncates output current pulse, electronically shorts output ground, displays error message front-panel display. PCX-6220 power-factor corrected. switch-mode design current source features internal stored energy, offers typical wall-plug output connector efficiency >70%. Safety features PCX-6220 include laser enable keyswitch, output cable safety interlock, remote interlock, delayed output enable.
