The Cosel PBA600F-48 is a 624W AC-DC enclosed power supply delivering 48V DC at 13A, engineered for industrial applications demanding stable, regulated DC power. This chassis-mount unit accepts universal AC input from 85V to 264V AC (1Φ, 47–63 Hz) or DC input from 120V to 350V DC, with built-in power factor correction and harmonic attenuation to IEC61000-3-2. Efficiency reaches 81.0% to 83.0% across operating conditions.
## Technical Specifications
• **Output:** 48V DC, 13A, 624W rated
• **Input:** 85–264V AC (1Φ) or 120–350V DC; 50/60 Hz nominal (47–63 Hz range)
• **Efficiency:** 81.0% to 83.0%
• **Adjustable Output Range:** 38.40V to 56.00V via built-in potentiometer
• **Protection:** Overcurrent (>105% rated or >101% peak; auto-recovery with 5-second continuous shutdown threshold), overvoltage (Vo+4.8V to Vo+12.0V activation), inrush limiting (thyristor-based), thermal derating with fan-fail detection
• **Power Factor Correction:** Built-in
• **Harmonic Attenuation:** IEC61000-3-2 compliant
• **Leakage Current:** Low-leakage option available (Code G)
## Key Features
• Output voltage adjustment via integral potentiometer or external resistor/supply methods
• Thermal shutdown protection with automatic derating based on current and temperature
• Fan options: long-life (F1), reverse air exhaust (F3), low-speed (F4)
• Compact form factor: 61mm W × 120mm D × 190mm H; approximately 1.6 kg
• Convection or fan-cooled operation
## Typical Applications
Industrial systems, telecommunications infrastructure, process automation, and other mission-critical applications requiring stable 48V DC regulation with integrated protection and harmonic compliance.
## Compatibility & Integration
Chassis-mount design for direct integration into cabinet and frame-based systems. Output voltage adjustment supports both local potentiometer control and remote sensing via external methods.
**Note:** Product is scheduled for manufacturer discontinuation around October 2028.
