Product Details

The PQ60120HPA20 PowerQor Peta half-brick converter is a next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The power dissipated by the converter is so low that a heatsink is not required, which saves cost, weight, height, and application effort. The Peta series converters offer industry leading output current for a standard “half-brick” module. In addition to typical single ouput voltage applications, the Peta units can also be used to provide a wide input range Intermediate Bus for IBA systems.

Operational Features

• Ultra-high efficiency, 92.5% at full rated load
• Delivers up to 240 Watts of output power (20A) with minimal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V, 100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI performance

Mechanical Features

• Industry standard pin-out configuration

Control Features

• On/Off control referenced to input side (positive and negative logic options are available)
• Remote sense for the output voltage compensates for output distribution drops
• Output voltage trim permits custom voltages and voltage margining

Safety Features

• 2000V, 30 MW input-to-output isolation (optional modules available with 2,250V isolation)
• UL 60950 recognized (US & Canada), basic insulation rating
• TUV certified to EN60950
• Meets 72/23/EEC and 93/68/EEC directives
• Meets UL94V-0 flammability requirements

Protection Features

• Input under-voltage lockout disables converter at low input voltage conditions
• Output current limit and short circuit protection
• Active back bias limit prevents damage to converter from external load induced pre-bias
• Output over-voltage protection
• Thermal shutdown
