NEWBASE Electric Bus AC System – Engineered for Ultimate Safety
NEWBASE sets the gold standard for safety in electric bus air conditioning with our multi-layered protection system:
Low-Voltage Protection
DC-DC conversion with overvoltage/overcurrent/short-circuit safeguards ensures stable operation even at 65°C ambient temperatures.
Military-Grade PTC Heating
IGBT-controlled heating system features comprehensive protections including voltage regulation, current limits, and dry-fire prevention.
Intelligent High-Voltage Distribution
Pre-charge circuits enable soft-start activation, while fused branch circuits provide fail-safe power allocation.
EMI Fortress Technology
360° shielding and equipotential bonding neutralize electromagnetic interference, guaranteeing electronic reliability.
Trust the system where every component is armored with redundant safety – because passenger comfort should never compromise operational security.
