With only 1A, what is it intended to drive?

ok102006

most wall-plug power adapter with small current should be okay
for example, iphone 5s, usb 3.0, both are using 5V and 1A

前面dc output 不是寫明 500mA (=0.5A) only? 是兩個 port 加上來先有一A.

所以我真是想不出有什麼用。

只是輸出十幾Watt 但 case 要咁大

0.5A?  Cant even charge a Samsung Note 3 or iPad.

供電俾router或者ok

應該兩個輸出share，即total 加埋出到1A，如只用一組便出到盡1A
用兩組安全計每組唔好多過500mA

註意越高A，noise亦相對較高。如只需用少過1A，買細好過買大

Pure speculation:

Given the massive heatsink for 12V/1A max, this is probably a shunt regulator. A shunt regulator will burn all the power as heat under no load, pretty much like a class A amp, so including the dropout voltage it'll dissipate more than 15W constantly.

The output port has 4 pins, so it's probably using a 4 wire scheme with 2 wires for voltage sensing, improving further the load regulation and lowering the output impedance further.

It will be an overkill to use a shunt regulator for CAS, which typically involve high current, and a (relatively) more effective series regulator would be sufficient for the job.

Ideal application for shunt regulators are typically below a few hundred mA, like buffers, line stage, pre-Amp, DAC, ... etc.

The first photo has shown it is powering the INT204.
Weiss INT204 USB(DoP) interface consumes about 0.15A

I thought audiophile loves overkill design?
PSU101 is an universal power supply, so it doesn't just built for INT202/203/204 digital circuit........the speculation is right.

好想比較吓 Toroidal Transformer 同埋 OCC 單晶銅鍍銀線 O 牛嘅分別。
