Product Parameters: Working voltage is DC12V, working current is <20MA, working frequency range is 20Hz‑400Hz, output mode is switch output.
Application: Intelligent trolley motor over-current detection, motor stall current detection, short-circuit detection, etc.
Easy To Install: The installation hole diameter is 3mm, the hole distance is 52.5mm, and the maximum detection wire diameter of the module is 5.2mm, which offers convenient operation and installation.
Stable Operation: The relay is closed when there is overcurrent, and the relay is released when there is no overcurrent.
STABLE FREQUENCY STANDARD: This 10MHz OCXO board delivers exceptional frequency stability with its constant temperature crystal oscillator design, making it ideal for accuracy timing applications in communication systems.
DUAL OUTPUT WAVEFORM OPTIONS: Features both sine wave output (10MHz/3dBm, 1Vpp) and rectangular wave output (10MHz/13dBm) with 50 ohm drive capability, providing flexibility for different signal processing needs.
ACCURACY VOLTAGE CONTROL: Equipped with a voltage controlled clock port for fine tuning frequency stability, ensuring high accuracy timing performance in applications.
ENHANCED SIGNAL PURITY: Constant temperature crystal oscillator incorporates a 7th order elliptical low pass filter to minimize noise and distortion, delivering cleaner and more stable output signals.
Good Replacement: Comes with stable structure, excellent performance and long service life, an ideal replacement for the old and damaged parts.
Circuit Setting: This module is applicable to 2S or 3S 3.7V lithium battery. Through short circuit setting, the default is 2 strings. When using 2 strings, the module can use its own battery equalization function, which is very practical.
LED Indicator: The red light is on when normal, the blue light is on during charging, the blue light is off when full, and the blue light flashes when abnormal is detected.
Current Setting: The indicates that the default current of the two parallel settings is 100K (0.9A) and 180K (0.5A). The resistor can be removed or replaced as required.

How to Choose the Best Conditional Access Modules
Installation and Setup
Installation is usually straightforward. First, ensure your TV or set-top box is turned off. Insert your subscription smart card into the CAM, ensuring it's oriented correctly. Then, insert the CAM into the CI or CI+ slot on your device. Power on your device, and the CAM should be automatically detected. You may need to navigate your device's menu to activate or register the CAM with your service provider.
Frequently Asked Questions
What is a Conditional Access Module?
A Conditional Access Module (CAM) is a hardware device that works with a compatible TV or set-top box to decrypt pay-TV channels. It works in conjunction with a smart card to authenticate your subscription.
Do I need a separate CAM for each TV?
Generally, yes. Each TV or set-top box that requires access to encrypted channels will need its own CAM and corresponding smart card to function.
How do I know which CAM is compatible with my TV?
Check your TV or set-top box manual for supported CI/CI+ standards and encryption systems. Most manufacturers list compatible CAM types in their specifications.
What is CI+?
CI+ (Common Interface Plus) is an enhanced standard that adds security features to the original CI interface. Many modern broadcasters require CI+ for their pay-TV services.
Can I use a CAM with any subscription card?
No, a CAM must be specifically designed to work with the encryption system used by your broadcaster, and it must be paired with the correct subscription smart card for that system.
