The SAFT Nife 162900/C (also identified by part numbers DS014F and RV1179) is a heavy-duty control and regulation circuit board designed for high-capacity industrial battery chargers and Rectifier-DC UPS systems. This board serves as the primary intelligence for large-scale power conversion units, managing the firing pulses for thyristor (SCR) bridges to maintain a precise DC output. Engineered for extreme reliability, it is typically found in SAFT Nife systems rated for high-power applications, such as the 249V / 380A configurations used in utility and oil and gas infrastructure.

Product Datasheet Summary

The 162900/C datasheet emphasizes its precision regulation capabilities, maintaining DC output stability within ±1% despite fluctuations in the AC mains. The “DS014F” designation identifies the specific PCB layout and hardware revision, while “RV1179” refers to the regulation and voltage-sensing sub-circuit. The board features adjustable potentiometers for “Float” and “Boost” charge voltages, allowing technicians to calibrate the charging profile to specific battery chemistries (such as Ni-Cd or Lead-Acid). Integrated LED indicators provide real-time status of the firing circuit and any active alarm conditions.

 

Country of Origin

This industrial power electronic component was manufactured in Sweden (Oskarshamn), the global headquarters and primary manufacturing site for SAFT Nife’s industrial battery and charger systems.

 

Application Fields

The RV1179 / DS014F series is critical for high-availability DC power systems:

• Electrical Substations: Providing reliable 220V/250V DC control power for switchgear and protection relays.
• Oil & Gas Platforms: Powering emergency lighting and critical shutdown systems in offshore environments.
• Power Plants: Serving as the central charging logic for large stationary battery banks used in black-start operations.
• Telecommunications: Managing the DC power plants for large-scale rural or industrial exchange hubs.

 

Product Usage Instructions

1. Installation: Ensure the charger is completely de-energized and the battery bank is isolated. Slide the 162900/C board into its card guides and secure the edge connectors.
2. Calibration: After installation, verify the “Float” voltage setting using a calibrated multimeter. Adjust the RV1179 potentiometers slowly to match the battery manufacturer’s recommended standby voltage.
3. Phase Sync: Ensure the AC synchronization inputs are correctly phased; improper phasing can lead to erratic firing pulses and “ripple” in the DC output.
4. Safety: High voltages (up to 249V DC and 380V+ AC) are present on the busbars adjacent to this board. Always use insulated tools and follow arc-flash safety protocols during live testing.

 

Technical Description

The 162900/C (DS014F) operates as a closed-loop PID controller. It samples the output DC voltage and compares it against a temperature-compensated reference. Based on the error signal, the board shifts the “alpha” firing angle of the thyristors. By advancing or retarding the gate pulses relative to the AC sine wave, the board can precisely control the amount of power delivered to the 380A load. The RV1179 sub-circuit specifically handles the voltage-sensing isolation, ensuring that high-voltage DC transients do not damage the sensitive logic components on the board.

 

Q&A – Frequently Asked Questions

Q: Can this board be used in a 110V DC system? A: No. The 162900/C is specifically component-scaled and calibrated for 249V nominal systems. Using it in a 110V system would result in “Under-voltage” trip conditions and improper regulation.

Q: What does the “/C” suffix indicate? A: In SAFT Nife nomenclature, the suffix usually denotes a specific hardware revision or a factory-set calibration for a specific customer requirement (e.g., specialized alarm delays).

Q: My charger has high AC ripple on the DC output. Is this board at fault? A: It is possible. If the firing pulses from the DS014F are inconsistent, the thyristor bridge will become unbalanced. However, you should also check the main DC filter capacitors and the thyristors themselves.

Q: Where can I source the SAFT Nife 162900/C and RV1179 boards? A: You can find the SAFT Nife 162900/C and other legacy charger components through specialized industrial power and DC system renewal parts suppliers.
