QC Series Compact Low-Power RF Driver QCXXX-YYDC-ZZZ-AAV

The QC series is a compact low-power RF driver for AOMs and acousto-optic Q-switches, covering24–110 MHz with up to24 W into50 Ω. Digital modulation, analog power control, zero-crossing synchronization, and configurable output power meet industrial, research, and OEM needs. Contact conduction cooling, compact construction, configurable modes, and integrated modulation provide reliability, heat dissipation, and easy integration in space-limited lasers and optoelectronics. Two TTL digital inputs support fixed-width pulses set internally or variable-width pulses controlled externally. Analog input continuously adjusts RF power. Factory-configurable modes include analog power control, switched analog control, first-pulse suppression, and prepulse elimination to improve laser output and control. Zero-crossing synchronization aligns RF pulses with RF zero crossings to reduce pulse jitter and improve repeatability and stability in timing-sensitive lasers. QC drives Q-switches for stable pulsed-laser generation and AOMs for pulse picking, high-speed intensity modulation, and precision control in industrial and ultrafast lasers, precision processing, research, and optoelectronics. Applicable devices:acousto-optic modulators and air-cooled Q-switches. ¹Voltage range corresponds to0%–100% of preset maximum RF power and applies to acousto-optic devices configured with A05,R05,and M05. ²Into50 Ω. ³ZC enables zero-crossing by default. Status LEDs:Red |Normal Operation;Green |Standby;Yellow |Fault. Mating plug:Molex0430251200 with Molex0430300008 crimp terminals. Heat-sink capacity required:36 W@12 V,45 W@15 V,72 W@24 V. Power/control connector:12 pins,3.00 mm (0.118") pitch. Unless stated otherwise, inputs reference GND; outputs are open-collector with maximum sink current25 mA. Pin1 |SYNC Output;Pin2 |FPS Trigger Input;Pin3 |Fixed-Width Modulation Input;Pin4 |GND;Pin5 |Variable-Width Modulation Input;Pin6 |Analog Modulation Input;Pin7 |Zero-Crossing Synchronization Enable;Pin8 |Low-Power Fault Output;Pin9 |High-Power Fault Output;Pin10 |High-VSWR Fault Output;Pin11 |Enable Input;Pin12 |VDC Supply Input. Absolute Maximum Ratings Note:exceeding limits may cause instantaneous, irreversible damage; DC feedback at the RF output is prohibited. Adjustments:RF Power Level |Clockwise increases output power. Low-Power Threshold |Below the minimum threshold, LP Fault goes low.* High-Power Threshold |Above the maximum threshold, HP Fault goes low. High-VSWR Protection Threshold |Sets load-mismatch tolerance; mismatch drives the fault low, turns the LED yellow, and stops output; enter standby and resume to reset. Fixed Pulse Width |Adjusts RF-off duration over1～20 μs. FPS/PPK-Only Adjustments:FPS Initial Power |Sets first-pulse output;FPS Slope |Sets recovery to normal RF power after FPS starts,20～300 μs;FPS Window |Sets suppression duration,20～300 μs. *Analog RF-power modulation automatically masks LP Fault. Ordering:XXX =024,027,041,068,080,or110 as standard, corresponding to RF frequencies24.00,27.12,40.68,68.00,80.00,or110.00 MHz.
