Power Modules

 

Size: 72 * 42 * 23mm

 

Module parameters

Module Properties: non-isolated step-down module (buck)

Rectification: non-synchronous rectification

Input voltage :4.5-60V (60V foot measured 61V will work)

Output voltage: (1) adjustable (1.25-30)

                          (2) fixed output (arbitrary choice between 1.25-30), (temporarily only for bulk orders).

Default shipping is an adjustable output.

Output Current: 3A. Can 30V 3A 90W at full load

Efficiency: Up to 92% (the smaller the pressure, the higher the efficiency) see the back of the specific test pattern

Switching frequency: 50KHz

Minimum pressure: 2V

Operating Temperature: Industrial (-40 Celsius to +85 Celsius) (output power 20W or less)

Full load temperature rise: 40 Celsius

Load regulation: +- 0.5%

Voltage regulation: +-0.5%

Output ripple:Input 48V Output 5V 3A ripple less than 10mV

20M-bandwidth

Dynamic response speed: 5% 200uS

Short circuit protection: current limiting, since the recovery (output voltage lower than 20V)

Output over-voltage protection: adjustable output without overvoltage protection, you can select the output with a fixed output overvoltage protection.

Input Reverse Polarity Protection: Yes.

Installation: screw (diameter 3 mm), 2 mounting holes, 2 holes spaced 82 mm fixed

Wiring: You can plug terminals, pressure lines, no welding

Shell: All aluminum, casting process, can work in harsh conditions

Weight: 120g
