Vigitron - Vi20101 - MaxiiGuard 1G Ethernet Surge Protector
Product Overview
The Maxii Guard Vi20101 is a compact, in-line surge protector designed to plug directly into 10/100/1000 Base-T ports. It supports high-power 802.3af/at/bt PoE up to 90W and provides a robust 20kA per pair surge current rating for both standard and extended Ethernet runs. Certified to EN61000-4-5 and EN55024 standards, it ensures reliable protection for mission-critical networked equipment.
Key Configuration
- • Network Compatibility: Supports 10/100/1000 Base-T Ethernet interfaces.
- • PoE Support: Compatible with 802.3af/at/bt standards (up to 90W).
- • High Surge Rating: 20kA per pair protection across all four pairs (1-2, 3-6, 4-5, 7-8).
- • Advanced Protection: Withstands 10KV common mode and 1.5KV differential mode surges.
- • Compact Design: Measures 1.23" × 1" × 3.5" and weighs 79 g (0.172 lb).
Key Features
The Vi20101 features a nominal line voltage of 44-57V with a 20kA maximum discharge current and ultra-low capacitance <1.5pF for signal integrity. It supports up to 2A on 4 pairs and offers flexible grounding via an M3 stud, shielded RJ45, or DIN rail. Fully certified FCC Class B, CE, RoHS, and designed to meet NEMA TS2 and UL497B standards, this module ensures high-performance surge suppression with minimal leakage.
Technical Context
It is an NDAA-compliant in-line surge protector that plugs directly into ports, eliminating the need for extra grounding cables. Compatible with Cat5 to Cat6a, it features a rapid <200ns response time and a failsafe short-circuit mode.
Installation Notes
Featuring dual male RJ-45 connectors, the Maxii Guard Vi20101 is built for extreme environments, operating from -40°C to +85°C at altitudes up to 5,000 meters. This IP40-rated module includes both a 35mm DIN rail adapter and a wall mount kit for flexible, high-density installation in rugged or industrial settings.
