3 / 6 page GE Energy Preliminary Data Sheet ACE184 Series Power Shelf Main Output: 600A; Standby output: 8A October 29, 2012 ©2012 General Electric Company. All rights reserved. Page 3 Status and Control Some features, such as programming of the output voltage, may be controlled both by hardware and firmware. Unless otherwise noted, control of the output voltage via the signal pin (Vprog) is ‘active’ and overrides as long as the signal voltage is ≤ 3Vdc. A firmware initiated command, attempting to change the output voltage will be ignored as long as the signal voltage (Vprog) is ≤ 3Vdc Details of analog controls are provided in this data sheet under Signal Definitions. GE Energy will provide separate application notes for the I2C protocol ( Document #97FS2855). Contact your local GE Energy sales representative for details. Note that most control and capability functions Signal Definitions All signals and outputs are referenced to Output return. These include ‘Vstb return’ and ‘Signal return’. Input Signals Note: Refer to the individual rectifier data sheets for supported features. Voltage programming (Vprog): An analog voltage on this signal can vary the output voltage of all modules. If 12V output CAR1812 or CAR1612 rectifiers are used, the output can vary ± 10% from 10.8Vdc to 13.2Vdc. The equation of this signal is: Vout = 10.8 + (Vprog * 0.96) 0 < Vprog < 2.5 If 2.5 < Vprog < 3, the output is 13.2V. If Vprog is > 3V or left open the programming signal is ignored and the unit output is set at the setpoint of 12Vdc. This signal is paralleled among the power supplies. Load share (Ishare): This is a single wire analog signal that is generated and acted upon automatically by power supplies connected in parallel. The Ishare pins are tied together among the power supplies in the shelf. No resistors or capacitors should get connected to this pin. Remote ON/OFF: Controls the presence of the main output voltage. This is an open collector, TTL level control signal. This signal needs to be pulled HI externally through a resistor. Maximum collector voltage is 12Vdc and the maximum sink current is 1mA. A Logic 1 (TTL HI level) turns ON the main output, while a Logic 0 (TTL LO level) turns OFF the main output. This signal is not overwritten by the firmware ON/OFF instruction. The default firmware setting is ON. An OFF command either through this signal or firmware would turn OFF the power supply. The default state re-initializes if bias power is interrupted to the processor. These signals are brought out independently for each power supply. Enable (ON/OFF): This is a short signal pin that controls the presence of the main output. This pin should be connected to ‘output return’ on the system side of the output connector. The purpose of this pin is to ensure that the output turns ON after engagement of the power blades and turns OFF prior to disengagement of the power blades. These signals are brought out independently for each power supply. Write protect (WP): This signal protects the contents of the EEPROM from accidental over writing. When left open the EEPROM is write protected. A LO (TTL compatible) permits writing to the EEPROM. This signal is pulled HI internally by the power supply. Note: only for factory programming. This signal is interconnected among the power supplies Output signals Output current monitor (Imon): A voltage level proportional to the delivered output current is present on this pin. The signal level is 150A = 3V when the CAR182 or CAR1612 rectifiers are used. These signals are brought out independently for each power supply. INPUT OK: A TTL compatible status signal representing whether the input voltage is within the anticipated range. This signal needs to be pulled HI externally through a resistor. These signals are brought out independently for each power supply. DC OK: A TTL compatible status signal representing whether the output voltage is present. This signal needs to be pulled HI externally through a resistor. These signals are brought out independently for each power supply. Over temp warning: A TTL compatible status signal representing whether an over temperature exists. This signal needs to be pulled HI externally through a resistor. These signals are brought out independently for each power supply. If an over temperature should occur, this signal would pull LO for approximately 10 seconds prior to shutting down the power supply. The unit would restart if internal temperatures recover within normal operational levels. At that time the signal reverts back to its open collector (HI) state. Fault: A TTL compatible status signal representing whether a Fault occurred. This signal needs to be pulled HI externally through a resistor. These signals are brought out independently for each power supply. This signal activates for OTP, OVP, OCP, AC fault or No output. Module Present: This pin is connected to ‘output return’ within the power supply. Its intent is to indicate to the system that a power supply is present. This signal may need to be pulled HI externally through a resistor. |
