Board-level design as a service: the topologies designed in-house (analogue control, SCR and thyristor firing, IGBT stages), how a board is specified with a customer, and what is handed over.

The control software itself: what the loop does between the measurement and the firing angle, how a setpoint is held, and what is configurable on site against what is fixed at design time. §1 pillar 1 claims firmware in-house; this is the paragraph that shows it.

The monitoring layer: what a unit reports, over which interfaces, and what an operator can do remotely against what still needs a visit. This is pillar 2 — 'digital by default' — made concrete.

Transformer and choke design and winding, in-house: what is calculated at design time when a requirement falls outside the standard range, the BSS-171 practice the designs are built to, and what a buyer must state before a quote — purpose, rating in kVA, primary and secondary voltage and frequency, and the site environment. The shop can wind to 1.2 MW.

The division of responsibility: the client specifies the ingress rating and usually the dimensions, and what we calculate is the sheet gauge and material for the site environment — proposing our own dimensions only where the client's are not physically possible. Then the thermal consequence of sealing a unit rather than ventilating it, and which finish suits which environment.

The obsolete-electronics service: what is captured from an installed unit, what is retained (tank, magnetics, enclosure) and what is replaced, and how a drop-in replacement is verified against the original.

What a factory acceptance test covers and who attends, and what commissioning on site involves — setpoints, alarm checks, handover documents. Describe the activity, never a site — and never how often a unit passes.
