Output and Naming Convention
CM1000 Series Functions and Connections
- J3-A +SENSEPositive Sense Line provides point-of-use output voltage feedback signal to unit when tied to (+) side of output load to compensate for voltage drop of output cables under load.
(+) and (-) sense lines should be routed as a twisted pair to mitigate pickup of ambient electrical noise (EMI).
Sense lines must be connected on power supply side of any output protection devices, fuses, circuit breakers, switches, relays, etc which may interrupt DC Output Current Path.
- J3-B -SENSENegative Sense Line (See J3-A above).
- J3-C CURRENT SHARECurrent Share Signal connects to current share terminal of additional unit(s) connected in parallel.
Forces equal sharing of output load current.
Return terminals (J3-F) of load-share unit(s) must also be mutually connected
Load share and return wires of parallel load-share units should be routed as twisted pair.
- J3-D N INHIBITInhibits output of unit when pulled low (connected to J3-F Return terminal).
- J3-E (NC)No Connection
- J3-F RETURNReturn Pin for all J3 functions
Standard Power Supply Notes
Abbott AC-DC switchers are designed to operate in a rugged military environment where a high degree of isolation, regulation and thermal performance is required. The extreme low-profile of these modules makes them an ideal choice in applications where space is limited, and reliability is a chief concern. These switchers represent a cost-effective, off-the-shelf alternative to costly DC-DC arrays . The units are fully compliant with MIL-STD 461, CE101, CE102 and also meet MIL-S-901(high impact shock), MIL-STD-810 and MIL-STD-1399, Section 300, type I requirements (spike voltage test).
Among key standard features are input power factor correction, full cycle holdup during power interruption, soft start/controlled inrush, and on-board in-line fuse. These state-of-the-art AC-DC switchers are well-suited for airborne, ground or shipboard systems.
Ambient Temperature – the temperature of the still air surrounding a power supply, measured a minimum of 4 inches (10.2 cm) from the supply. Note that these Abbott supplies are conduction-cooled and that temperature specifications refer to baseplate temperature, not ambient temperature.
Efficiency – the ratio of total output power, expressed as a percentage. Efficiency must be
specified at a specific combination of load and input voltage.
Isolation – the electrical separation between the input and output of a power supply due primarily to the power transformer. The isolation is a function of materials and spacing throughout the supply.
Line Regulation – the maximum change in output voltage, expressed as a percentage of output voltage, that occurs as the input voltage varies over its specified limits, with load and temperature constant.
Load Regulation – the change in output voltage, expressed as a percentage of output voltage, that occurs as the load changes from minimum to maximum, at constant line and constant temperature. Load change may be specified for other than no load to full load as, for example, 50% load to full load.
Mean Time Between Failure (MTBF) – the failure rate of a power supply, expressed in hours, predicted as prescribed by MIL-HDBK-217.
Periodic and Random Deviation (PARD), or Ripple and Noise – the unwanted periodic (ripple) or aperiodic (noise) deviation on the power supply output voltage from its nominal value. Ripple is a function of the input line and switching components. PARD is expressed in millivolts peak-to-peak or rms, at a specified bandwidth (typically 20 MHz).
Over-Voltage Protection (OVP) – a protective feature that shuts down a power supply (reduces the output voltage to a minimal level) to prevent damage to the load when the output voltage exceeds a predetermined limit.
Short-Circuit Protection – a protective feature that limits the output current of a power supply to prevent damage to the supply caused by short circuits. There are two types of short-circuit, or overload, protection depending on the power supply:
- Foldback Current Limiting protects switching regulator power supplies from damage when an overload occurs by reducing, or folding back, both the output voltage and current as the load.
resistance ranges from maximum to short circuit.
- Constant Limiting Current protects power supplies from damage when an overload occurs by holding the output at a constant predetermined maximum current level.
