GL Series: Single & Multi Output Switchers
The new GL series provides a broad range of AC/DC power
supply solutions that covers power ratings from 25 watts to
250 watts for use in various industrial applications requiring
standard footprint size and very high reliability.
These low-profile AC/DC switchers offer universal input
voltage with no switches or jumpers, ideal for higher volume
worldwide applications.
All models feature:
• Industry standard footprints
• Universal input
• Full power to 50°C
• High demonstrated MTBF
• Automatic overvoltage protection
• Overload protection
• Built-in EMI Filtering
• Extensive safety approvals
• Derated operation to 70°C
• ±2% regulation on main output
• 250 VA size enclosed
• Two year limited warranty
Many models feature:
• EN61000-3-2 Compliance
• Supervisory outputs (5 V/12 V)
• Wide-adjustable floating 4
th
output
• Single wire current share
• Remote Sense
• Adjustable main output
• Power Fail and DC Good signals
• Wide-adjustable on single output models
Certifications and Compliances
•
- UL 60950-1
•
Certified, ITE
- CSA C22.2 CSA 60950-1
