The LR series is an isolated DC-DC converter with wide input range, tight regulation and six-sided shielded case. These modules have trim and control features. Single and dual isolated output models are standard. They can operate up to 5W over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling. • Up to 3.33:1 input voltage range • Six-sided shielded case • Control feature • Trimmable output • Input/output isolation • Single and dual isolated output • No external components required • No heat sink or derating required Contact Pico for part number of available options: • Expanded operating temp: -55°C to +85°C Stabilization Bake Temperature Cycle Burn-In • Special Input Voltage, Output Voltage, Isolation Voltage or Output Power 2025 REV 1 www.PicoElectronics.com | Series LR&nb
