Feature: Made of high-quality electronic components, can maintain stable performance in harsh environments. High efficiency, conversion efficiency up to 90%. Compact size, easy to install on most electric device. The product is suitable for: ADC / DAC / operational amplifier, RS232 RS485 RS422 bus, low power audio power supply, etc. This product is suitable for DIY refitting your equipment. Module built-in thermal shutdown function, current limit function, soft start function, frequency compensation, output voltage is more stable. Specification: Input voltage is 3~24V, Output voltage: ±5V / ±6V / ±9V / ±10V / ±12V / ±15V / ±18V ± 24V (Optional) Maximum output power: 1-8W Conversion efficiency: 70-90% Quiescent current: 3-4mA Accuracy: ±3% positive voltage, ±5% negative voltage Working frequency: 400KHZ Working environment temperature: -40~ + 85℃ Package list: 1 * Module Note: The actual product color may deviate from the photo due to light. There may be a slight deviation in the measurement of product. Input voltage cannot be greater than the maximum input range. Output power cannot be greater than the maximum load for a long time. Input power must be greater than output power because of the power consumption of the module itself. In order to obtain a more stable voltage, it is recommended that the output be greater than 10mA.
