A1: Prosurge offers a comprehensive SPD product line to address needs ranging from residential to mission-critical infrastructure. The main series and their positioning are as follows:
POSP 20 Series: Plug-on UL1449 Type 1 SPDs designed for residential and light commercial applications. They can be directly plugged into mainstream load centers (breaker panels), providing convenient primary protection for an entire home or small facility.
PSP B / 20PSP Series: Compact Panel SPDs suitable for low to moderate exposure environments. Their compact size and waterproof plastic enclosures make them ideal for commercial, industrial, and telecommunications applications. The 20PSP features a nominal discharge current (In) of 20kA, while the PSP B has an In of 10kA.
PSP C / HPSP Series: High-Performance Panel SPDs designed for critical commercial and industrial environments. They offer higher surge current capacity (PSP C up to 300kA per phase, HPSP up to 600kA per phase) and optional features like EMI/RFI filtering and metal enclosures for superior protection.
PS Series: Ultra-High Capacity Panel SPDs intended for mission-critical applications. Featuring a modular design (SMTMOV/HSMTMOV), this series boasts the highest surge capacity (up to 900kA per phase) and unique Anticipatory Failure Monitoring (AFM) technology with a three-stage status indication (Blue – Yellow – Red) to ensure continuous, reliable protection.
PSP E / PSPF Series: Extra-Compact SPDs. The PSP E is specifically designed for single-phase systems, while the PSPF offers various protection mode combinations. Both are ideal for protecting sensitive equipment like commercial LED lighting, telecom devices, HVAC systems, and medical electronics where space and cost are key considerations.
