Technical Specifications | Parameter Category | Specification / Inference | | :--- | :--- | :--- | | Product Type | High-Current Switched-Mode DC/DC Converter | | Product Family | ABB CP Series. 2TAZ is the definitive family prefix. | | Standard | IEC 62368-1, IEC 61204-7 | | Input Voltage (Uin) | Defined by 220406. This is a different input code from the previous 220301 models. This strongly suggests a different nominal input voltage. A probable interpretation is: • 2204 may correspond to a 220 V DC nominal input system (e.g., with a wide range of 180-300 V DC). • Alternatively, it could be a variant of 110V DC input. Verification from official data is critical. | | Output Voltage (Uout) | Regulated 24 V DC. The code R4504 is interpreted as follows: • R: Regulated output. • 45: Likely a high-power sub-series or product variant code. The output voltage is almost certainly the industry-standard 24V DC. • 04: Likely indicates the output current rating. In this common encoding, 04 typically corresponds to 4.0 A. However, given the 45 series code, the current could be higher (e.g., 10A, where 10 might be coded differently). A plausible and common high-power configuration is 24V/10A (240W). | | Output Current (Iout) | Likely 10.0 A (A strong possibility for a 45 series high-power module). A secondary possibility is 4.0 A (if 04 is taken literally, but this would be lower power than R2504 inferred earlier, which seems inconsistent). | | Output Power (Pout) | Estimated 240W (If 24V/10A). This is a substantially higher power module compared to the ~50W and ~100W versions previously discussed. | | Output Characteristics | • Precisely regulated voltage. • Protections: Short-circuit, overload, overvoltage, overtemperature. • Isolation: Reinforced galvanic isolation. • Low output ripple. | | Efficiency | > 88% (typical for higher-power units). | | Mounting | 35 mm DIN Rail (EN 60715), but may require more space for heat dissipation. | | Terminations | Larger screw-clamp terminals or possibly busbar connections for high-current output. | | Cooling | May incorporate a fan for forced-air cooling, given the high power density. | | Operating Temperature | -25°C to +70°C (with possible derating at high ambient temps). | | Protection Degree | IP20. | | Status Indication | Multiple LEDs (Power, Output OK, Fault). | | Safety Approvals | CE, UL, cULus. | | Typical Application | Used in large control cabinets or switchgear to power extensive 24V DC systems, such as: • Multiple protective relays and meters. • A large PLC system with numerous I/O racks. • Multiple contactors with DC coils. • Network switches, HMIs, and other ancillary electronics. |

Its purpose is to prevent damage to external control devices if a fault occurs in that circuit. Breaking Capacity (Icn) Typically 6 kA or 10 kA at 400V AC for the base GSE203 model.

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. |

This is the most critical parameter to verify. It is highly likely a common industrial DC voltage. Based on pattern: • A very strong possibility is 110 V DC (with a wide range, e.g., 80-150V DC). • Other possibilities: 24V DC, 48V DC, or 220V DC. Must be confirmed via datasheet or nameplate. | | Output Voltage (Uout) | Regulated 24 V DC. The code R2251 is key: • R: Regulated. • 22: Likely a sub-series or design code. The output voltage is most probably the industry-standard 24V DC, not 22V. • 51: Likely indicates the output current rating. 51 often decodes to 5A (where 5=5A, 1=version or check digit). | | Output Current (Iout) | Likely 5 A (Inferred from 51 in R2251). | | Output Power (Pout) | Approximately 120W (If output is 24V/5A: 24V * 5A = 120W). | | Output Characteristics | • Voltage regulated (±1-2%). • Short-circuit, overload, and overvoltage protected. • Galvanic isolation (typically 3-4 kV). • Low ripple and noise. | | Efficiency | > 85% (typical for this class). | | Mounting | 35 mm DIN Rail mounting. | | Terminations | Screw-clamp terminals. | | Operating Temperature | -25°C to +70°C (Industrial temperature range). | | Cooling | Natural convection (fanless). | | Protection Degree | IP20. | | Status Indication | LED power indicator. | | Safety Approvals | CE, UL, cULus. | | Typical Application | Installed in: • Low-voltage switchgear (e.g., MNS). • Motor control centers. • Automation cabinets.

A typical decoding is: • C: Front-mounted rotary handle for manual operation. • 25: Likely a specific handle type or accessory package code. • A: Often indicates the inclusion of standard accessories. For GSH series, A commonly means the contactor is supplied with: - Auxiliary Contacts (typically 2 NO + 2 NC). - Mechanical Interlock provision or specific mounting配件. Rated Operational Current (Ie) 400 A (at AC-3, 400V). This is the key rating of the GSH204 frame. Rated Operational Voltage (Ue) Up to 690 V AC Control Coil IMPORTANT: The model GSH204 -C25A does not specify the coil voltage or type. This is a critical missing specification.
