Sensata Engineering Solutions for High-Density Datacenters
As compute power density scales up to 100+ kW per rack driven by AI/ML cluster deployments, conventional infrastructure protection and thermal management are no longer sufficient.
As compute power density scales up to 100+ kW per rack driven by AI/ML cluster deployments, conventional infrastructure protection and thermal management are no longer sufficient. Modern hyperscale datacenters demand sub-millisecond fault isolation, non-intrusive current/pressure sensing, and extreme thermal resilience.
At GVZ Components, as an authorized distribution partner for Sensata Technologies, we provide system designers and system integrators with high-reliability hardware components engineered specifically for Power Distribution Units (PDUs), Uninterruptible Power Supplies (UPS), Liquid Cooling Units (CDU), and Immersion Tanks.
1. Advanced Power Protection & Circuit Breakers (PDU / Rack PDU / UPS)
Standard thermal circuit breakers suffer from ambient temperature derating, leading to nuisance tripping inside hot rack environments (up to 60°C). Sensata’s Airpax™ hydraulic-magnetic circuit breakers utilize a magnetic solenoid and a hydraulic delay core, making trip current thresholds independent of ambient rack temperatures.
Key Product Series & Technical Specifications:
-
-
Application: Low-profile power distribution for 1U/2U Rack PDUs and high-density power strips.
-
Current/Voltage Ratings: Up to 100A continuous at 240VAC/415VAC and up to 80VDC/125VDC per pole. High-power versions (LELHP) handle up to 125A in compact footprints.
-
Interrupting Capacity: AIC ratings up to 10,000A to safely isolate high fault currents.
-
Certifications: UL 489 listed (branch circuit protection) and UL 1077 recognized (supplementary protection).
-
-
-
Application: Heavy-duty main utility feed protection in centralized UPS systems and modular power skids.
-
Features: Multipole configuration with auxiliary switches for remote telemetry monitoring (trip state indication into DCIM/BMS software).
-
2. Liquid Cooling & Immersion System Sensing (CDU & Direct-to-Chip)
Direct Liquid Cooling (DLC), Rear Door Heat Exchangers (RDHx), and Two-Phase Immersion Cooling require continuous monitoring of fluid pressure, delta-P across pumps, and fluid leakage risks.
Key Product Series & Technical Specifications:
-
-
Technology: Micro-Electro-Mechanical Systems (MEMS) piezoresistive technology with stainless steel hermetic seals (no internal O-rings, preventing fluid degradation).
-
Pressure Ranges: 0–10 bar to 0–50 bar relative/absolute pressure ranges suitable for dielectric fluids and glycol/water mixtures.
-
Output Signal: Standard 4-20mA, 0.5-4.5V ratiometric, or I²C/SPI digital interface for direct integration into embedded pump controller microcontrollers.
-
Accuracy & Stability: Total Error Band (TEB) $< \pm 1.0\%$ across the $-40^\circ\text{C}$ to $+125^\circ\text{C}$ operating range.
-
-
-
Form Factor: Sub-miniature TO-220 package for direct PCB or heat-sink mounting.
-
Function: Physical over-temperature protection with positive snap-action bi-metallic contacts to trip thermal shut-off logic independently of software loop failures.
-
3. Solid-State Switching & High-Voltage Direct Current (HVDC) Isolation
Modern "Green" Datacenters are transitioning toward 380VDC microgrids to reduce AC/DC conversion losses. Isolating high-voltage DC loads requires arc-extinction technology and solid-state reliability.
Key Product Series & Technical Specifications:
-
-
Application: Silent, bounce-free switching for auxiliary heating elements, rack fans, and line conditioning in precision air handlers (CRAH/CRAC).
-
Ratings: Up to 95A @ 660VAC with zero-voltage or random turn-on options. Integrated overvoltage transient protection (TVD/MOV).
-
-
-
Technology: Gas-filled hermetically sealed contactors using ceramic cavity technology for rapid arc extinction.
-
Ratings: Isolation voltage up to 1500VDC with continuous current carrying capability from 50A to 1000A+.
-
Application: Emergency disconnect and isolation in battery energy storage systems (BESS) and high-voltage DC busbar architectures.
