Code name: Seasonic Power Angel Test Kit
This pack included a triple rail electronic DC load at fixed consumption of 120W along of a wall-plug basic power meter, Seasonic deliver several sponsored kit to young PSU reviewers of 2003, AC Watt measurement this in comparison to 120W of fixed DC load, this gave first ever opportunity so consumers to perform basic power efficiency evaluation.

a) 120W of fixed DC load this was offered at housing (metal box) at the shape and dimensions of a regular 300W PSU.

b) Wall-plug basic power meter, this had socket pins for American power system 110V.
This become known later on as Kill-a-Watt - P4460 meter.
Kill-a-Watt - P4460 = Made in Taiwan technology of 2001.
(Seasonic Power Angel Test Kit this become EOL after 2006).
The purpose of that test kit was Seasonic technological progress to be shown in public, due comparison due measurements, of their products VS any competitors, PSU products which had worst efficiency.

At 2006 and later, Stand-by power consumption this become of high importance too.
No other PSU brand did such a move in the past 20 years, in favor of consumers education.

Its DC load per rail circuit, this is based at equivalent concept of what it does LM723 when this is driving a single 2N3055.
But specific circuit IC's I will speculate that they use of pulse modulation instead.

I would expect to see such a gadget made by Fluke calibration.  ;D
But it seems them not monitoring specific market.
