Delta Next Generation PJ Series Open Frame Power Supplies
200% Power Boost for Reliable Start-Up
Industrial systems rarely operate under steady conditions. Motors, solenoids, and capacitive loads often require high inrush currents at startup, forcing designers to oversize power supplies just to handle short peak loads.
Delta’s next-generation PJ Series open frame power supplies solve this challenge with an integrated 200% power boost capability, delivering short-term peak power for demanding startup conditions-without requiring oversized power supplies.
Available through FORTEC Switzerland, the PJ Series enables compact, efficient, and reliable power architectures for modern industrial equipment.
Designed for Real Industrial Startup Conditions
Many industrial applications experience short peak loads during system startup:
- Conveyor motors in logistics systems
- Solenoids in packaging machines
- Compressors and refrigeration systems
- Measurement and test equipment
Conventional power supplies must often be over-dimensioned to handle these peaks.
The PJ Series eliminates this constraint.
Its integrated Power Boost technology delivers up to 200% of rated output power for up to 10 seconds, providing the necessary reserve power during startup events while maintaining compact system design.
This approach reduces:
- Power supply oversizing
- System cost
- Installation space requirements
Flexible Industrial Power Architecture
The PJ Series supports a wide range of industrial system designs.
Output Power Options
- 100 W models
- 150 W models
Output Voltages
- 12 V
- 24 V
- 48 V
Wide Input Voltage Support
- 85 - 264 VAC
- 120 - 373 VDC
This flexibility allows the PJ Series to integrate into diverse industrial infrastructures and power architectures.
Compact Low-Profile Design for Space-Constrained Systems
Industrial control cabinets and embedded systems often have strict space limitations.
The PJ Series addresses this challenge with a low-profile open frame design of only 27 mm height, enabling easy integration into compact equipment.
Additional system integration advantages include:
- Built-in remote ON/OFF control
- Low inrush current and low leakage current
- High power factor and high efficiency
- Optional open frame or enclosed configurations
Built for Harsh Industrial Environments
Industrial installations frequently expose power supplies to dust, moisture, vibration, and temperature extremes.
To ensure long-term reliability, the PJ Series incorporates several protection and durability features:
- -40 °C cold start capability
- Conformal-coated PCBA to protect against dust and chemical contaminants
- Robust mechanical design for industrial machinery
- Convection cooling design
The conformal coating process protects sensitive electronic circuits from contamination and environmental stress, preserving long-term system performance.
Global Compliance and Safety
The PJ Series is designed for international deployment and complies with major safety and EMC standards:
- IEC / EN / UL 62368-1
- Japan PSE (DENAN) compliance
- IEC / EN 61000-3-2 Class A harmonic current emissions
These certifications simplify regulatory approval and enable reliable integration into global industrial systems.
Typical Applications
The Delta PJ Series is suitable for a wide range of industrial systems, including:
- Packaging machines
- Conveyor and logistics systems
- KIOSK machines
- Refrigerated display cabinets
- Industrial automation equipment
- Test and measurement systems
Its combination of compact design, high efficiency, and startup power reserve makes it ideal for modern industrial power architectures.
