SITOP

Industrial Power & DC UPS

24 V DC power architectures selected around load current, inrush, buffering and diagnostics.

Honghao reviews steady-state load, simultaneous inrush, redundancy, selectivity and outage-bridging requirements before selecting the supply and add-on modules. Exact input range, output current and approvals are confirmed by article number.

Decisions that change the BOM.

Review these points before choosing a model name or requesting a replacement.

01How do I size a 24 V DC power supply for a PLC panel?
24V PLC power supply sizing

Create a load schedule for continuous current and simultaneous inrush, include branch behavior and future spare capacity, then check input network, ambient derating, redundancy, selectivity and diagnostics. Nameplate current totals alone can miss startup peaks.

02When is a SITOP DC UPS needed?
SITOP DC UPS selection

Use a DC UPS when short outages must not stop controls immediately, or when the PLC, HMI or industrial computer needs time for controlled shutdown. Define protected loads, bridge time, battery or capacitor strategy, diagnostics and maintenance responsibility.

Review DC UPS parameters
03What is electronic selectivity in a 24 V system?
24V DC selectivity PLC panel

Selective protection separates overloaded or shorted 24 V branches so a single fault is less likely to collapse the whole control supply. Branch current, cable, inrush, trip behavior and diagnostic integration must be coordinated with the power supply.

Quotation and compatibility

The information needed for a technically usable offer.

What should I send for a SITOP quotation?
SITOP quotation

Send the full article number for replacements. For a new application, provide load current, input supply, availability, diagnostics, quantity, destination and required delivery date. Honghao will identify assumptions before confirming the BOM.

Send product or application data
How does Honghao verify SITOP compatibility?
SITOP compatibility check

The review checks the complete article number, product generation, required accessories, electrical and communication interfaces, lifecycle status and the surrounding system. Final ratings remain tied to current manufacturer documentation and the approved BOM.

See the BOM verification method
Can SITOP products be supplied inside a complete control panel?
SITOP control panel

Yes, when the contracted scope includes panel engineering. The design basis should define power, protection, environment, interfaces, drawings, programming responsibility, FAT and export documentation before assembly.
