THTAK lithium UPS — our own product line

Why we build our own line

Most UPS suppliers in Hong Kong are traders — they resell whatever the catalogue happens to include. We run a production base in Shenzhen, which changes what we can offer in three concrete ways:

• The specification is negotiable. Output voltage (100/110/120/127 V for overseas or low-voltage sites), cabinet dimensions, battery capacity, socket types — these are build parameters, not special orders.
• Lithium is designed in, not retrofitted. Our ET1 and LT500 ship with LiFePO4 cells and a matched BMS from the start, rather than a lead-acid chassis with a lithium pack squeezed in.
• Factory-direct means one responsible party. The unit, the battery and the BMS come from the same production line — when something needs attention, there is no brand-agent finger-pointing.

The trade-off is honest to state: THTAK does not carry the brand recognition of EATON or APC. What you get instead is a specification that actually fits, at a factory-direct price, with the same local installation and maintenance team behind it.

What the current line covers

The table above lists the series we build regularly:

• D1 / D2 / D3 kVA — online double-conversion with selectable low-voltage output (100–127 V), for overseas equipment and sites wired to non-HK standards.
• ET1 — 3–6 kVA online UPS with LiFePO4 batteries built in; rack and tower versions.
• LT500–LT1500 — line-interactive units with lithium cells built in, for network racks, shops and surveillance.

Custom builds

For anything outside the standard line — unusual voltage, extended runtime, a cabinet that must fit a specific rack, a vehicle or marine installation — tell us the duty and we build to it. Typical custom parameters:

• Output voltage and frequency (including 60/50 Hz variants)
• Runtime and battery chemistry (LiFePO4 standard; VRLA where the budget rules)
• Form factor — rack, tower, wall-mount or vehicle-mount
• BMS parameters, communications (SNMP / Modbus) and socket layout

Lead times are quoted at specification stage, usually two to four weeks for custom builds. Send us the requirement — the load, the runtime and the space available — and we will come back with a buildable specification and price.
