96V 20A Programmable DC Power Supply, Adjustable Buck Converter with Wireless Control
DPH8920 Programmable DC Buck Power Module
The DPH8920 series is a DC-input programmable buck power module with a 20-110 V DC input and 0-96 V adjustable output. The DPH8920 variants support up to 20 A and 1920 W. Actual output depends on the input source, load, and cooling conditions; do not assume maximum voltage, current, and power are available simultaneously.
Input requirement: this product requires an appropriate DC source within the specified input range. It is not designed for direct connection to AC mains. Confirm the required DC input source and complete package before ordering.

My first impression after opening and installing batteries was that this meter is very well built considering the price and manufacturer. I had read some reviews stating that it's amp measurements were not accurate below 5 amps, I haven't seen any issues in any measurements I've taken, even side by side with my fluke meters. I've successfully taken accurate amp, voltage and continuity measurements with this ETCR6920B, the display is nice and legible. I haven't tried storing data and making transfers to a PC yet, the soft case is good enough for storage on a shelf and the test leads are of good quality and rated for 1000v. There's nothing bad to say about this meter especially when you consider the price, it's a really great meter.
Works as described.
