SPECIFICATIONS

Ac Input 85-264 Vac, 47-63 Hz single phase.

Input Current Maximum input current A at 90 Vac, 60 Hz with full rated load. Input current harmonic content meets the requirements of IEC1000-3-2 Class A for all load conditions.

Hold-upTime 25 ms minimum from loss of ac input at full load, nominal line 115 Vac . Minimum Load No minimum load required

Output Power 250 W fan cooled, 180 W convection. See chart for models under 12 V.

Overload Protection Fully protected against short circuit and output overload. Short circuit protection is cycling type power limit or foldback type depending on model and output. Recovery after fault is automatic. Individual output current limits are a function of load distribution and degree of overload.

Output Noise rms, 1% pk-pk, 20 MHz Bandwidth, differential mode. Measured with noise probe directly across output terminals of the power supply.

Transient Response Main us typical response time for return to within of final value for a 50% load step change, Di/Dt< A/us. Maximum voltage deviation is

Remote Sense Provided as a standard feature. Capable of compensating for V total of cabling losses in voltage.

Overvoltage Protection Built in on all models. Output voltage decay is dependent upon loading.

Voltage Adjustment Main output

Efficency Minimum 80% on 12-48 V units, 75% on 5 & V units at full rated load.

Input Protection Internal ac fuses provided on all models. Fuses do not blow on overload or short blow only if catastrophic failure occurs in the unit.

EMI/EMC Compliance All models include built-in EMI filtering to meet emissions requirements:

Inrush Current Inrush 240 Vac is less than 37 A, averaged over the first ac half-cycle under cold start conditions. Limiting provided by internal thermistors.

Fan Output An additional 12 Vdc, 250 mA output suitable for powering a dc fan is included in all models.

Thermal Shutdown Provided as a standard feature. Designed to protect unit from prolonged over temperature.

Power Fail TTL or CMOS compatible output goes low V 8 ms before output voltage drops more than 4% below nominal voltage upon loss of ac power. The signal is factory set to trip when input power can no longer sustain the output.

Temperature Coefficient / °C typical on all outputs.

Leakage Current 70uA under normal conditions 132 Vac 60 Hz . Maximum under single fault conditions 264 Vac 60Hz , 250 uA.

Power Good TTL/CMOS compatible output goes high more than 100 ms after V1 reaches the under voltage threshold and should assure that sufficient energy is stored in the input section to provide normal power fail/shutdown. The signal will fall to a low state V when V1 goes below 95% of the rated voltage.

External Off TTL/CMOS compatible input shuts down power converter. A logic high V with 400 uA source shuts down the power converter. A logic low V or an open circuit allows the supply to run. V & 5 V models require 25 mA source.

All specifications are typical at nominal input, full load at 25OC unless otherwise stated
