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).

Note 1: Line and load regulation is limited by duty cycle quantization and does not indicate a shift in the internal voltage reference.
Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: [email protected]).
Note 3: If the output voltage falls below the Output DC Current Limit Shutdown Voltage for more than 50ms, then the unit will enter into hiccup mode, with a 500ms off-time.
Note 4: Higher values of isolation capacitance can be added external to the module.
