DC±10V 0-22MA Rechargeable Analog Signal Generator Signal Source High-Precision Analog Source Calibrator

DC±10V 0-22MA Rechargeable Analog Signal Generator Signal Source High-Precision Analog Source Calibrator

Rechargeable Version:
- Can be connected to external 24V power supply
- Support PC's USB port, phone chargers, power banks, etc. (micro USB socket for Android)
- Built-in battery. You can check electric quantity of the battery. Turn on the battery switch, press the MODE button for 1 second, the digital tube will flash and display the battery voltage for 5 seconds. The relationship between the battery indicator and the power level: green: more than 90% power; yellow: more than 40% power; red: less than 40% power
- Lithium battery charge and discharge over-current protection, automatic charge management, power indicator. When fully charged, the device automatically stops charging

New Functions:
- The voltage output range is increased from 0-10V to ±10V which can be set. Convenient for debugging forward and reverse rotation
- 0V output can be achieved. It outperforms those products of single power supply. The control dimmer can be completely off, and motor speed can be completely static
- The shell is made of ultra-thin frosted ABS material, the upper and lower covers are seamless, and the high-end feel is good
- The software adds a custom quick adjustment function, which can be set to output only a few values, which is convenient for quick debugging and production

Features:
- Various output ranges can be set. Voltage -10V to +10V (0-10V by default). User can set to 0-10V, 2-10V, 0-5V, 1-5V, 0-3.3V, 0-2.5V, 0-1V, ±10V, ±5V, -10V to 0V. Current 0-22mA (0-20mA by default). User can set it as 0-20mA, 4-20mA, and 0-22mA
- Display modes can be set: actual voltage, current display, percentage display, frequency display, other customized display methods
- This signal generator can be output by passive or active wiring, compatible with 2-wire, 3-wire, 4-wire system; can directly simulate passive 2-wire pressure sensor, temperature sensor, etc.; can be connected to active 3-wire, 4-wire PLC , inverter, servo driver, flow valve, etc.
- Output with short-circuit protection, power supply with reverse-connection protection
- Power supply modes: 1. DC15V-30V external power supply. Can share the 24V power supply of PLC and other equipment. 2. For Android (micro USB) universal interface. Can be connected to power banks, chargers, computer USB port, etc. 3. Built-in 1000mAh /3.7V lithium battery (Optional. The charging and discharging circuit is reserved, and the user can access it by himself. When the external power supply is connected, the battery is automatically charged). Attention: Only one power supply method works, and the above power supplies can also be connected at the same time.
- One-key switching of voltage and current adjustment; independent wiring, and simultaneous output
- Coarse and fine adjustment modes, and the number of turns can be set separately
- Customize the quick adjustment mode. You can use the shortcut output mode to manually adjust the output, up to 9 points can be set
- 0.4" 4-digit digital tube, 0.01 precision adjustment. Linear output can be calibrated. High-quality high-definition digital tube with uniform brightness. Encoder stepless knob adjustment, performance and service life are N times better than ordinary potentiometers
- Output short-circuit protection, 24V input reverse-connection protection
- Ultra-thin matte non-slip shell is beautiful and elegant. High-grade aluminum alloy knobs, electroplated buttons, featuring comfortable feel
- It can solve problems: continuous speed regulation of servo motor forward & reverse; the dimmer light cannot be turned off; motor shakes or even rotates slightly
- Imported chips works stably for a long time. The signal generator adopts high-power MOSFET, industrial-grade brand power chip and CPU chip, and current loop chip, with high precision and good stability; it can work in harsh environments for a long time without interruption
- When the power is off, you can press the knob to save and store the power-on output value. As long as the knob is not pressed, when the instrument is turned on next time, it saves the last manually stored value
