MPS1076-000 300Watt Built-in UPS
(PS/2 Case, ATX-Style Connector,Contact-
Closure-Compatible Control Interface.)
MPS1076-000 is a plug-in replacement for conventional NLX/ATX form-factor
switching power supplies. Units function as a normal power supply
when AC line input is present and as truly on-line UPS during periods of
power failure. Suitable for operation in conjunction with Magnum 24V
battery packs.
Features:
300W Continuous DC Output Power* . Active PFC . Full UPS functionality . Wide-ranging AC
Input (47Hz to 63Hz, 90V to 260V) . Five DC Outputs . High power Standby Output (+5Vsb /2.5A) . Hold-up
Time >16ms (No Battery Fitted) . Efficiency >65% (AC/DC & DC/DC) . Overtemperature, Overvoltage &
Overcurrent Protection (Latched Shutdown) . Fan Speed Control . Standard UPS Contact Closure
Compatible Interface . Logic On/Off . PS/2 (NLX) Style Case . ATX (NLX) 20-Way Motherboard Connector
* Output power derated by -5W/°C above 25°C

7. Control Interface
| PSON (LOGIC ON/OFF) |
BI-UPS® Input. TTL compatible siganl setting on/off state of unit.DC outputs enabled if pulled to logic low. DC outputs (excluding +5Vsb) disabled if driven to logic high or open circuited. |
| Power Good |
BI-UPS® Output. TTL compatible flag indicating status of +5V and +3.3V outputs. Set to logic high between 100ms and 500ms after both +5V and +3.3V outputs reach normal operating limits. Reset to logic low at least 1ms prior to either +5V or +3.3V outputs dropping out of normal operating limits. |
| Interface Enable |
BI-UPS® Input. Discrete signal to enable BI-UPS® control interface. Interface inactive if open circuited or held at logic low (-5 to -15V). Interface enabled if driven to logic high (+5 to +15V). |
| AC Fail |
BI-UPS® Output . RS232 compatible flag indicating failure of ac line voltage. ‘AC normal’ condition indicated by logic high (+5 to +15V); ‘AC fail’ by logic low (-5 to -15V) |
| Battery Backup Low |
BI-UPS® Output. RS232 compatible flag indicating battery backup voltage low. ‘Battery normal’ condition indicated by logic high (+5 to +15V); ‘Battery Low’ by logic low (-5 to -15V). |
| Shutdown |
BI-UPS® Input.Discrete signal enabled during battery back-up operation only. No action taken if held at logic low(<1V) or Open circuited. BI-UPS® shutdown initiated if driven to logic high (+5V to +15V). |
