Input voltage: 6-40VDC
Output voltage: continuously adjustable (1.2-35VDC) below 32V for a long time (applicable to applications where the input voltage is higher than the output voltage and cannot be boosted)
Output current: maximum 20A, long-term within 15A (please add a fan to dissipate heat when the power tube temperature exceeds 65 degrees, and use a reduced rating for high voltage output)
Current limiting range: 0.2-20A (adjustment) please add a fan if the module exceeds 65 degrees
Using DDS algorithm, the frequency step value can reach 0.001HZ, and the frequency stability is good.
This product can not only output 7.830Hz Schumann wave, but also adds programmable frequency modulation technology, which can adjust the frequency in the range of 0.001Hz~200KHz (it can also be used as an ordinary programmable digital signal generator).
Digital crystal frequency reference, more stable and stronger anti-interference;
The power interface adopts DC5.5 x 2.1 interface, which is easy to use. The USB end can be plugged into the power supply or USB charging head or other USB power supply devices to work.
