NOTES: 1.
Under Voltage Lock Out (UVLO) is approx. 10.5-13.5 Vdc.
Vin = 28±1 V dc. Nominal output power: P
= 20W, P+
= 5W, P-
= 5W.
Full power output must be equal to or less than 30 watts. Short duration Aux current is 2A peak.
Over-Voltage Protection (OVP) guaranteed by design not to exceed 6V dc on main output under any static condition at room
temperature. On models with OVP option, only. Therefore this parameter is limited to <5.5V on these models.
Short Term Over-Load (STOL).
Continuous overload. Auxiliary outputs are protected with thermal shutdown.
Internal Pull-Up typically 22k ohms to V
. For 80-volt transients, input device must be able to sink at least 3.5 mA.
Internal Pull-Up approximately 22k ohms to typically 12V. This is an open collector, TTL compatible, edge triggered active low
input. A valid low must exist for 20% to 80% duty ratio. The converter takes approximately 2 mS to synchronize. For "TTL
Sync" option V
≤
55V.
Time for outputs to reach 90% of final value. Measured from valid Inhibit High V
