MAX-750 Multiple Output
NON-STOCK ITEM; SPECIAL ORDER ONLY
NOT FOR NEW DESIGNS
FEATURES:
• Over 4 watts/in3 power density
• 80% overall efficiency
• VMEbus and Multibus II system compatibility
• Meets international safety agency requirements
• All outputs fully regulated ±1%
• High peak current for motor starting
• Ac automatic line selection option
SPECIFICATIONS:
INPUT
Ac Input: 90-132 Vac/180-264 Vac, 47 to 63 Hz. User selectable.
See option “A” for automatic line selection. Internally fused for 15 A.
Inrush: Cold start ac current is less than 90 A at 115 Vac and
30 A at 230 Vac. Limited by thermistor.
Holdup Time: 16 ms minimum after removal of power, at
nominal line, full load.
Efficiency: 80% typical.
Brownout Protection: Holds regulation to 85 Vac or 170 Vac.
OUTPUT
Adjustability: User adjustable ±5% minimum.
Line & Load Reg: ±1% over ac input range and 0 to 100% load
change. Output #1 requires minimum load of 10%.
Ripple & Noise: Less than 1% p-p or 100 mV, whichever is
greater.
Remote Sense (Output #1): Compensates for 250 mV total line
drop. Open sense lead protection.
Temperature Coefficient: 0.02% per degree C.
Stability: 0.1% over 8 hours after 30 minutes warm-up.
Transient Response (Output #1): Output voltage returns to
within 1% in less than 500 µs for a 50% load change. Peak
transient does not exceed 5%.
Overload Protection: All outputs are protected against overload
and short circuit. Automatic recovery upon removal of fault.
Overvoltage Protection (Output #1): Protects load against
power supply induced overvoltage. Trip point is factory set so that
output voltage cannot exceed 136% of nominal.
Remote Inhibit: Contact closure to the negative sense line
drops output power to nominal zero.
Reverse Voltage: Protected against reverse voltage up to supply
current rating.
ENVIRONMENTAL
Thermal Protection: Shuts down power supply if overheated.
Automatic recovery.
Temperature Range: 0° to 50°C at full ratings. Derate to half
power at 70°C.
Safety Agencies: Most models are approved to UL1950; CSA
22.2 #234; IEC 950 and TÜV EN60950, Class 1 SELV., CE 72/23/
EEC/93/68EEC (low voltage directive).
Conducted RFI: Meets FCC Part 15, Subpart J, Class A;
EN55022 Class B; CISPR 22 Class B.
Cooling: 30 cfm required to achieve full ratings.
Output Isolation: Isolated from ground 50 Vdc.
OPTIONS:
Option “A”, Ac Auto-Range: Automatically selects proper ac
line voltage range to enable power operation at either 115 or 230
Vac without user intervention.
Option “P”, Ac Power Fail: Provides TTL “0” 5 ms before
output voltage goes out of regulation band upon loss of ac power.
VMEbus compatible, provides 48 mA sink current capability. Not
available if option “G” is selected.
