• Strong driver power for a sealed type outdoor system
• Designed for 12 V input power and addition of a separate booster circuit (Power Amplification and Booster Circuit)
• Booster transformer has useful function, auto impedance matching and selection of T / R
• Limiter circuit to prevent over signal at input port of a receiver
• This application is operated by the trigger signal from main system and self trigger function is not necessary. It is simply compared with Free Run Mode. (Trigger Pulse Width: about 1 ms TTL signal recommended)
• Two control parts
- VR1 : Control Ultrasonic Frequency P.T.C (Positive Temperature Coefficient) series resistance can be compensated for temperature.
- VR2 : Preset of receiver gain. Some case it can be replaced with fixed resistor.
- Receiver Amplifier Mode (VGA / Non VGA) also can be selected
- 3 types of receiver signal outputs are available but generally V-pul or T-pul is useful
