Technical Specifications | Parameter Category | Specification / Inference | | :--- | :--- | :--- | | Product Type | Switched-Mode DC/DC Converter | | Product Family | ABB CP Series (Control Power). 2TAZ is the definitive family prefix. | | Standard | IEC 62368-1, IEC 61204-7 | | Input Voltage (Uin) | Defined by 222301. • This code segment is identical to the previously analyzed 2TAZ222301R2631. • Therefore, the input voltage is highly likely the same: 24 V DC nominal (with a wide range, e.g., 18-36 V DC). This module is designed to be powered from a 24V DC system. | | Output Voltage (Uout) | Likely 24 V DC. The code R2254 is interpreted as: • R: Regulated output. • 22: Likely a sub-series or product variant code. As with R2631, the actual output voltage is most probably the industry-standard 24V DC. • 54: Likely indicates the output current rating. In common encoding, 54 could correspond to 5.4 A or be coded for 5.0 A (where 5 = 5A, 4 = version/check). | | Output Current (Iout) | Likely 5.0 A or 5.4 A (Inferred from 54 in R2254). This is a higher current output compared to the R2631 (~3A) model within the same 222301 input family. | | Output Power (Pout) | Approximately 120W - 130W (If 24V @ 5A/5.4A: 24V * 5A = 120W). | | Output Characteristics | • Precisely regulated voltage. • Protections: Short-circuit, overload, overvoltage, overtemperature. • Isolation: Galvanic isolation between input and output (typically ≥ 3 kV). • Low output ripple. | | Efficiency | > 85% (typical). | | Mounting | 35 mm DIN Rail (EN 60715). | | Terminations | Screw-clamp terminals capable of handling the higher output current. | | Cooling | Natural convection (fanless) or possibly a small fan, depending on thermal design. | | Operating Temperature | -25°C to +70°C | | Protection Degree | IP20. | | Status Indication | LED(s) for input power and output status. | | Safety Approvals | CE, UL, cULus. | | Typical Application | Used in control systems where the primary available DC source is 24V, but a higher-power, isolated 24V output is required. Common in: • Powering a large PLC system with multiple I/O racks from a 24V battery-backed bus. • Supplying a group of protective relays and meters in a substation automation cabinet. • Creating a dedicated, clean 24V bus for sensitive instrumentation, isolated from a noisy main 24V supply. |
