Description
This component is a signal processing unit designed for systems requiring precise frequency filtering, amplification, and conversion. It plays a crucial role in ensuring stable transmission and reception of signal input during operation.
### Electrical Characteristics
Operating voltage: 12–24 V DC with ±10% tolerance. Current consumption: 0.8 A max under standard load conditions. Input/output impedance rated at 75 ohms nominal for compatibility with industry-standard components.
### Physical Interface Specifications
Connection type: screw terminal block or solder pad (depending on model configuration). Dimensions: compact profile—40 mm x 50 mm x 20 mm housing made from ABS plastic casing for EMI shielding. Weight: ~150 g inclusive of mounting hardware. Thermal dissipation via integrated heatsink section; no active cooling necessary.
### Environmental Parameters
Temperature range: functional within −10°C to +60°C ambient conditions; storage limit up to −30°C minimum and +80°C maximum. Humidity resistance verified under non-condensing conditions (5–95%). Shock resistance calibrated per industrial-grade standards IEC XYZ guidelines.
- Not suitable for outdoor installations without additional protective housing options.
- Non-adjustable gain levels—fixed configurations only.
- Limited bandwidth coverage outside the defined operating frequency parameters of X Hz to Y Hz.
- Signal degradation may occur if exposed directly to high electromagnetic interference sources.
