What this product is

What this product is

The DZY24100B incorporates multi-stage EMI suppression, a robust boost APFC pre-regulator, and an isolated DC-DC resonant converter topology. Governed by high-precision closed-loop control circuitry, it enforces tight voltage regulation, active autonomous load sharing, and comprehensive hardware protections against AC over/undervoltage, output OVP, overtemperature, and continuous short circuits in compliance with major telecom standards.

What problem it solves

Eliminates network downtime caused by severe utility voltage fluctuations in remote base stations, mitigates 24V DC bus voltage sags under sudden dynamic load steps, resolves unequal module current distribution in multi-shelf arrays, and prevents thermal runaway in high-density telecom cabinets.

Who and where it is for

Tailored for 24V telecom BTS installations, optical transmission hubs, microwave repeaters, SCADA and RTU automation enclosures, industrial 24V DC bus systems, and mobile emergency communications trailers.

Core advantages

  • Wide AC input range (90V-290V) withstands severe grid fluctuations in remote base stations
  • Two-phase interleaved APFC topology delivers high conversion efficiency ≥ 92.0%
  • Advanced DSP digital control and master-free active current sharing support hot-swappable parallel operation
  • -25°C to +65°C operating temperature with intelligent fan cooling prevents thermal breakdown in harsh cabinets
