Technical Specifications | Parameter Category | Specification / Inference | | :--- | :--- | :--- | | Product Type | Switched-Mode DC/DC Converter (Single Output) | | Product Family | ABB CP-S / CP-C Series (Control Power Supplies). 2TAZ is the definitive family prefix. | | Standard | IEC 62368-1, IEC 61204-7 | | Input Voltage (Uin) | Defined by 220301. Highly likely to be 110 V DC nominal with a wide input range (e.g., 80-150 V DC). This is the most common interpretation for this code segment within this family, matching standard 110V DC control systems. Other inputs (24V, 48V, 220V DC) are possible but less likely for this specific code; verification is essential. | | Output Voltage (Uout) | Regulated 24 V DC. The code R2321 is interpreted as follows: • R: Regulated output. • 23: Likely a sub-series or product variant code. Crucially, the actual output voltage is almost certainly the industry-standard 24V DC, not 23V. • 21: Likely indicates the output current rating. In this common encoding, 21 often corresponds to 2.1 A or is coded for 2.0 A (where 2 = 2A, 1 = version). | | Output Current (Iout) | Likely 2.0 A or 2.1 A (Inferred from 21 in R2321). This is a lower current rating compared to the R2251 (5A) and R2504 (4A) variants. | | Output Power (Pout) | Approximately 48W - 50W (If output is 24V @ 2A/2.1A: 24V * 2A = 48W). | | Output Characteristics | • Precisely regulated voltage. • Protections: Short-circuit, overload, overvoltage. • Isolation: Galvanic isolation (≥ 3 kV). • Low output ripple. | | Efficiency | > 85% (typical). | | Mounting | 35 mm DIN Rail (EN 60715). | | Terminations | Screw-clamp terminals. | | Operating Temperature | -25°C to +70°C | | Cooling | Natural convection (fanless). | | Protection Degree | IP20 (for mounting inside an enclosure). | | Status Indication | LED for "Power On" / "Output OK". | | Safety Approvals | CE, UL, cULus. | | Typical Application | Used in control cabinets to power a moderate load of 24V DC devices, such as: • 1-2 mid-sized protective relays (e.g., ABB REF615). • A small PLC with a few I/O modules. • A collection of sensors and indicators. |
