18-36 V
Input
50 V
Output
10 A
Current
The IQ24500HZx10 InQor® Zeta converter is an isolated,
fixed switching frequency DC-DC converter that uses
synchronous rectification to achieve extremely high
efficiency and power density. The 24 Vin modules feature
2,250 Vdc isolation and low common mode noise. The
Zeta series converters offer industry leading useable
output power for any standard “half-brick” module. RoHS
compliant (see last page).

Half-brick
DC-DC Converter
Operational Features
• Ultra-high efficiency, 94% at full rated load current, 95%
at half rated load current
• Delivers up to 10 A of output current (500 W)
• Wide input voltage range: 18 – 36 V, with 50 V
100 ms input voltage transient capability
• Fixed frequency switching provides predictable
EMI performance
• No minimum load requirement means no preload
resistors required
• Wide output voltage trim range (-50% to +10%),

IQ24500HZC10 Module
Protection Features
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection protects
converter and load from damage and consequent
hazardous conditions
• Active back bias limit provides smooth startup with
external load induced pre-bias
• Latching output over-voltage protection protects load
from damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Safety Features
• 2250 V, 30 MΩ input-to-output isolation
• UL 60950-1:2003, basic insulation
• CAN/CSA-C22.2 No. 60950-1:2003
• EN60950-1:2001
• CE Marked
• RoHS compliant (see Page 12)
