CP-S.1 24/5.0 supply selection: load budget, protection and DC distribution
ABB CP-S.1 24/5.0, order code 1SVR320561R1000, is a DIN-rail primary switch-mode power supply delivering 24 V DC at 5 A and 120 W. ABB catalog data specifies a wide input range of 100–240 V AC or 100–250 V DC. The supply is part of a CP-S.1 family with multiple current ratings; use the exact 5 A code for selection and replacement.

Match the exact ABB designation, system role, electrical limits, approved accessories and revision. Do not infer interchangeability from appearance or a shared family prefix.
CP-S.1 24/5.0 can supply control electronics, sensors, I/O and other 24 V DC loads when the calculated demand and transient profile fit the unit. Include startup current, simultaneous load, voltage drop, selectivity and reserve capacity in the DC budget. Redundant operation requires suitable external redundancy components and a defined failure strategy.
Selection and compatibility checks
For 1SVR320561R1000, check AC/DC input type, rated output current, total wattage, ambient temperature, mounting clearance and any required approvals. ABB lists up to 94% efficiency for the CP-S.1 range and a DC OK signaling output; confirm details in the applicable data sheet. Do not choose a supply solely by the sum of nominal steady-state currents.
For CP-S.1 24/5.0, establish the equipment boundary before procurement: record the host controller or panel, the connected field device, the installed hardware and firmware revisions, the supply source, the protection method and the required operating sequence. A family-name match is not enough to confirm that CP-S.1 24/5.0 is a compatible replacement. Check all interfaces and accessories against the exact ABB documentation.
Commissioning and acceptance
Before energizing CP-S.1 24/5.0, verify polarity, protective earth, input protection and downstream branch fusing. Measure output voltage under representative load and test the DC OK signal. Label the source and distribution circuits, and document the power budget and any redundancy scheme.
A practical acceptance record for CP-S.1 24/5.0 should include the nameplate photograph, order code, terminal and connector condition, configuration or setting values, software revision where applicable, test equipment and measured results. If CP-S.1 24/5.0 is installed as part of a larger system, record the system-level response as well as the local device indication.

Procurement and maintenance handover
When requesting a quotation for CP-S.1 24/5.0, provide the full designation, ABB order number, quantity, installed revision, application voltage, connected load or field-device type, required approvals and delivery destination. Ask the supplier to confirm that the supplied CP-S.1 24/5.0 matches the stated hardware and accessory configuration. Do not substitute a neighboring family code without engineering review.
