Precision Climate Control, Simplified: Meet the NB-015C5A-CPY04 by NEWBASE

When every degree matters—from vaccine transport to frozen food delivery—reliability can’t be compromised. The NB-015C5A-CPY04 from NEWBASE Auto Electronics is a purpose-built 3-in-1 refrigeration control module that unifies high-voltage DC/DC power conversion, variable-speed compressor management, and PTC heating control into a single, field-proven platform designed for the rigors of electric commercial mobility.

Unlike conventional systems that rely on separate boxes and complex wiring, the CPY04 delivers end-to-end thermal intelligence in a compact footprint—making it the ideal solution for OEMs and fleet operators transitioning to zero-emission cold chain logistics.

What Makes the CPY04 Unique?

🌡️ Adaptive Refrigeration Logic

• Setpoint range: –20°C to +20°C with automatic display of cabinet temperature
• Compressor speed dynamically adjusts based on ΔT = (Cabinet Temp – Set Temp)
  • Full cooling (5000 RPM) when above setpoint
  • Reduced speed (4500 RPM) near target
  • Shutdown when below –1°C (configurable fan behavior)
• Initial startup protocol: 90 seconds at 3000 RPM for system stabilization

❄️ Smart Defrost System – Automatic & Manual

• Auto-defrost cycle: Starts after user-defined interval (default 1 hour); triggers if defrost sensor < set temp
• Defrost duration: User-configurable from 1 to 30 minutes
• Termination conditions: Sensor >10°C or timer expires
• Post-defrost drip wait: Adjustable 1–10 minute drain phase with drain hole heater activation
• Manual defrost: Available when ambient <6°C (adjustable)
• ⚠️ Note: Defrost settings are retained after normal shutdown—but not if powered off mid-cycle

⚡ Robust 1500W DC/DC Power Core

• Input: 300–750Vdc (compatible with 400V/800V EV platforms)
• Output: 27.5V ±0.3V / 55A (1500W continuous)
• Efficiency: 96% typical at 540Vdc and ≥50% load
• Protections:
  • Output OVP (31–33V) / UVP (17–19V) – self-recoverable
  • Overcurrent: 60±5A
  • Short-circuit: Lockout after 10 cycles; reset via power cycle
  • Thermal: Derate >85°C, shut down >100°C, recover <90°C

📶 Full Vehicle Integration Ready

• Dual CAN2.0 buses (CAN1 & CAN2) for VCU/BMS communication
• 35-pin AMP connector supports:
  • 4 Electronic Expansion Valves (EEVs)
  • Condenser & evaporator fan control (high-side + PWM)
  • PTC heater, compressor heater band, drain hole heater
  • Door open signal, clutch/wake, pressure switches
  • Multiple NTC sensors (indoor, outdoor, defrost, discharge, suction)
• On-device diagnostics via query button: cycle through temps, voltages, speeds, currents, and fault logs

🛡️ Safety & Serviceability Built In

• Complies with automotive safety standards for HV systems
• Requires 1000V/50A fuse on HV input (per spec)
• Cover must be installed before power-on to prevent shock
• All fault states clearly indicated via front-panel icon and code “1”
• Non-recoverable faults: 24V supply over/undervoltage (>31V or <21V for >3s)

Applications That Demand Precision

• Electric medical refrigerated vans (WHO-compliant cold chain)
• Urban grocery & meal-kit delivery fleets
• Airport tarmac cargo chillers
• Mobile laboratories and blood transport units
