Manual: Dvb01 User

The DVB01 is a multifunctional digital voltage monitoring controller used for precision voltage measurement and circuit control. It is widely used in charge/discharge monitoring, overvoltage/undervoltage protection, and automated voltage relay switching. Key Technical Specifications

The following specifications are commonly cited by manufacturers and technical guides:

Measurement Range: DC 0–100V with a measurement accuracy of ±0.1plus or minus 0.1

Operating Voltage: Available in versions for DC 5V, 12V, or 24V power supplies. Load Capacity: DC: 0–30V / 10A. AC: 0–250V / 10A.

Power Consumption: Typically less than 90mA at 5V; drops to less than 3mA when the display is closed to save power.

Time Delay: Adjustable suction and disconnect delays from 0–99.9 seconds. Operational Functions The device features five core programmable functions ( ) to manage the on-board relay: Voltage Measurement (

): Continuously monitors and displays the current DC voltage. Charge Monitoring (

): Relay activates when voltage rises above the set upper limit and deactivates below the lower limit. Discharge Monitoring (

): Relay activates when voltage drops below the set limit, often used for battery protection. In-Range Suction (

): Relay stays active ("On") only when the voltage is between the upper and lower limits. Out-of-Range Suction (

): Relay stays active ("On") only when the voltage is outside the set limits (either higher than the upper or lower than the lower limit). User Setup & Tips

Calibration: You can calibrate the display to match a reference voltmeter by entering the

mode and adjusting the flashing digits with the [+] and [-] buttons. dvb01 user manual

Auto-Save: All programmed parameters (limits, delays, functions) are automatically saved to internal memory and will not be lost during a power failure.

Stability Tip: If your load and the DVB01 share the same power source, inductive loads (like motors) can cause voltage drops that reset the module. In these cases, it is recommended to add a 470uF/35V electrolytic capacitor between the DC+ and DC- terminals.

The DVB01 is a multi-function voltage monitoring relay (voltage comparator) designed to monitor DC voltages and trigger a relay output based on set thresholds. Technical Specifications

Power Supply: Requires a DC supply of 5V, 12V, or 24V depending on the specific model variant.

Input Range: Capable of monitoring DC voltages typically from 0V to 100V (actual range depends on configuration). Relay Output Capacity: DC: 0V–30V / 10A. AC: 0V–250V / 10A. Operating Modes (P-1 to P-5)

The module features five primary functions that can be programmed: Introduction : This section provides a brief overview

P-1 (Voltage Monitoring): The relay pulls in when the measured voltage is between set limits and releases when outside them.

P-2 (Voltage Threshold): Often used for over-voltage or under-voltage protection.

P-3 (Voltage Calibration): Allows the user to calibrate the displayed voltage value against a known source.

P-4 / P-5 (Delay Settings): Short and long presses of [SET] and [SW1] are used to adjust delay times (T1 and T2) before the relay acts. Programming Instructions

Enter Menu: Long press the [SET] button to enter the function selection mode.

Select Function: Use the [+] or [-] buttons to cycle through P-1 to P-5.

Adjust Values: Short press [SET] to enter a specific parameter. The flashing digit indicates which value is being modified. Use [SW1] to move between digits.

Save: Once values are set, long press [SET] to save the program and return to standard operation mode. Wiring & Stability Tips

Common Power Issues: If the module and the load share the same power supply, high-current loads (like motors) can cause a voltage drop that resets the DVB01. Solutions: Use separate wiring for the module and the load.

Add a 470uF/35V (or higher) electrolytic capacitor between the DC+ and DC- terminals to stabilize the input.

4.2 Connection Setup

1. Identify the output connector on the DVB01.
2. Using a shielded cable, connect the DVB01 output to the input of the device under test (e.g., a mixing console input, a patch bay, or a transmitter input).
3. Ensure the destination device is powered on and ready to receive signal.

2. Channel Scanning

The core function of the DVB01 is finding digital channels. The manual will describe:

• Auto scan: Searches all frequencies; takes 2–5 minutes.
• Manual scan: Used if auto scan misses channels; requires knowing your local transmitter’s frequency.
• Country/region setting: Incorrect settings yield no channels.

Common issue: “No signal” often means the antenna is weak or the scan mode (DVB-T vs. DVB-T2) is wrong. The manual’s troubleshooting table should list this.

3. Technical Specifications

(Note: Specifications may vary slightly by hardware revision)

• Operating Voltage: 9V DC (Standard 6F22 battery).
• Output Level: Adjustable, typically ranging from -60dBu to +4dBu.
• Frequency Response: Optimized for standard test frequencies (e.g., 400Hz, 1kHz).
• Connectors:
  • Audio Out: XLR Male/Female or BNC.
  • Monitoring: Headphone jack (3.5mm or 6.35mm).
• Current Consumption: Low power draw, optimized for long battery life during field use.
