Sensata Gigavac GV124FPX

Sensata Gigavac GV124FPX is a 200A 100VDC High Voltage DC Contactor from the GV12 series, built for DC power systems that use a 48VDC control supply. This model is a practical choice for telecom backup equipment, auxiliary battery cabinets, compact power distribution modules, low-voltage energy systems, and industrial DC control assemblies. The High Voltage DC Contactor combines an SPST-NO contact arrangement, 48VDC coil, PCB pin termination, sealed construction, and a no-auxiliary-contact configuration.

GV124FPX is best used where the system needs reliable 100VDC-class switching but does not require a separate auxiliary feedback contact. The main contact remains open until the coil is energized, allowing the controller to connect or isolate the DC path during start-up, shutdown, service, or fault response. For 48V-controlled systems, this High Voltage DC Contactor gives engineers a focused option without adding unnecessary signal wiring.

Product Positioning

GV124FPX should be positioned as a 48V coil High Voltage DC Contactor for compact DC distribution and backup power control. It is different from the 12VDC GV124BPX and 24VDC GV124CPX versions because its coil is matched to 48V auxiliary power architectures. This makes it suitable for systems where 48VDC is already available from a battery rack, telecom supply, controller module, or industrial DC bus.

The 200A current rating makes GV124FPX suitable for medium-current DC power paths, while the 100VDC voltage class keeps it focused on lower-voltage battery and distribution systems rather than large 800V storage cabinets. As a no-auxiliary-contact High Voltage DC Contactor, it is appropriate for designs that monitor operation through voltage sensing, current sensing, controller state, or system response instead of a dedicated contact position signal.

Features and Benefits

The 48VDC coil is the main reason to select GV124FPX. Many telecom, backup power, battery cabinet, and industrial control systems use 48VDC as a standard auxiliary supply. Choosing a High Voltage DC Contactor with a matching coil voltage can simplify the control design and reduce the need for additional voltage conversion.

The sealed GV12 construction supports dependable switching in environments where dust, humidity, vibration, or long operating hours may affect electrical components. A sealed High Voltage DC Contactor helps protect the internal contact system from outside contamination, which is useful in backup power cabinets, equipment rooms, mobile power modules, and enclosed industrial panels.

PCB pin termination helps support compact and repeatable OEM assembly. Instead of using larger control harnesses, designers can integrate GV124FPX into a board-supported power-control module or enclosed switching assembly. This can make the layout cleaner and improve production consistency for repeated equipment builds.

The no-auxiliary-contact configuration keeps GV124FPX simple. In many 48V-controlled applications, the system can confirm switching behavior through bus voltage, load current, or controller logic. If the design does not require a separate feedback contact, this High Voltage DC Contactor avoids extra wiring and keeps the product configuration focused.

Applications

GV124FPX is especially suitable for 48V backup power and telecom-style DC systems. In a battery backup cabinet, this High Voltage DC Contactor can isolate a battery string, connect a protected DC branch, control an auxiliary load, or disconnect equipment during maintenance. The 200A rating provides useful capacity for compact power systems without requiring a larger high-current platform.

This model can also be used in industrial DC distribution, low-voltage energy modules, mobile service equipment, charger support circuits, battery test fixtures, and auxiliary power units. In these systems, GV124FPX provides controlled switching for 100VDC-class circuits where the available coil supply is 48VDC.

For equipment manufacturers, GV124FPX can serve as a main disconnect in smaller systems or as a branch isolation contactor in larger assemblies. The final role depends on the current level, duty cycle, protection method, and control sequence. When used with suitable fusing, wiring, and precharge strategy where required, this High Voltage DC Contactor can support clean and reliable DC power control.

Selection Guide

Before selecting GV124FPX, confirm that the application is within the 100VDC and 200A class. Review continuous current, peak current, inrush current, switching frequency, thermal rise, load type, and protective device coordination. Capacitive loads may need a precharge path, while inductive loads may require additional system-level protection.

The coil supply should be a stable 48VDC source. If the equipment uses 12VDC control power, GV124BPX may be more suitable. If the equipment uses 24VDC control power, GV124CPX may be a closer match. The PCB pin format should also be checked for soldering method, mechanical support, vibration conditions, and clearance requirements.

If contact status feedback is required, GV124FPX may not be the correct version because it does not include auxiliary contacts. For monitored disconnect systems, choose a related GV12 model with auxiliary contact functionality. For simple 48V-controlled switching, GV124FPX remains a compact High Voltage DC Contactor option.
