An undervoltage lockout of approximately 7 VDC keeps system

current levels low during startup. Low line dropout typically occurs

at approximately 12 Vin to 17 Vin depending on model. See

Figures 12, 16 and 17.

Under short circuit conditions of 130% or more of full load

current, the converter will protect itself by shutting down. Short

circuit duration should be brief because power dissipation may

cause internal temperatures to rise rapidly. Restart is automatic

upon removal of the short circuit.

The MHV Series converters are capable of providing other

output voltage options in addition to those characterized on this

datasheet. Contact your sales representative to discuss other

output voltage options, www.interpoint.com/contacts.

Interpoint converters may use one or more of the following US
