Linear Power Supply Module AC-DC Positive Negative Voltage Regulator Adjustable

Description: Description Linear Power Supply Module AC-DC Positive Negative Voltage Regulator 220V To ±5V 3.3V Adjustable Attention: - Due to acrylic and heavy transformer, please check the module carefully as you receive it. -The module interface is clear and the performance is stable. Please use the information provided by our store to do functional verification under the corresponding experimental conditions. - The basic parameters of this module are in the following description, and the module information PDF file is provided. Project files are not provided. Buyers can consult customer service if they have operational problems. - Before using the module, please read the details page of this module to understand the power supply and usage restrictions to avoid damage to the module due to improper operation. - The modules in our shop are guaranteed to provide real module parameters, functions and pictures, and all modules are tested and shipped. Module Description: This module uses a 3m and a 5mm acrylic board to fix the power supply for protection. The module structure is more compact, more durable, and its service life is extended. Equipped with a 3-digit digital tube voltage display, it is more convenient to read. The module can be divided into 8V/2.5V/3.3V low voltage output area, positive and negative ADJ adjustable voltage area (positive voltage: +1.25V to +15V range adjustable, negative voltage: -1.25V to -15V range adjustable) , ±5V output area, the highest output current is 1A, the output current is determined by the load. Module Parameters: - Module name: Multiple-way linear power supply - Module type: linear power supply - Input voltage 220V (AC) - Output voltage: multiple channels (1.8V, 2.5V, 3.3V, ±5V, ±ADJ adjustable) - Output current: * 500mA (1.8V, 2.5V, 3.3V) * ±500mA (±5V) * ±500mA (±12V) - Output power: 10W (total power must not exceed 10W) - Static power consumption: mostly LED power indicator power consumption - Switching frequency: None (Linear power supply does not have this parameter) - Output ripple: better than 5mV (no load) - Module protection: None - Module features: multiple (multi-channel output; low noise, low ripple; with power indicator; with digital tube display) - Module application: various (precision operational amplifier power supply, high-speed/high-precision data converter power supply, MCU power supply, etc.) - Module weight: 680g - Module size: 150 x 100 x 55mm (LxWxH) - Module heating: the greater the load, the greater the heating - Working temperature: 0â to 70â (civilian grade) - Module interface: Input: 5.08-2P; Output: USB-A female, 2.54 double-row pin (straight) 2*15P Package Included: - 1 x Linear Power Supply Module Precautions: (1) The module is powered by 220AC, please pay attention to using electricity safely. (2) There is no reverse connection and over-current protection at the output of the module, please check it carefully before connecting to a load 3) The total output power of all channel power supplies cannot exceed the total power of the transformer (10W), otherwise the ripple will be too large or the transformer will be damaged. (4) When using the low-voltage output area, Switch 1 and Switch 3 need to be turned on. FAQ: Q1: The adjustable range display of ADJ is 5V at least, and the digital tube will not light up even if there is lower voltage. Can the voltage be output normally? A1: ADJ can output a voltage below ±5V, the lowest is ï¹¢1.25V, but the digital tube cannot display a voltage below 5V Q2: After ±5V output 500mA, the output voltage of ADJ will not reach 15V. Why?. A2: Since the voltage will decrease after the transformer outputs a certain power, the highest voltage of ADJ will also decrease accordingly. Q3: I accidentally burned one power supply, can the other power supplies be used normally? A3: Each power supply is independent. Generally speaking, as long as it is not a short-circuit damage, other power supplies can be used normally.
