15、1INTRODUCTION This manual contains instructions for the operation and maintenance of the 600W, 1KW, 2KW, 2.5KW, and 5KW EMS power supply series manufactured by Lambda EMI, Inc. of Neptune, NJ. The EMS series has been developed specifically for laboratory test and burn-in applications. The EMS supply

16、 produces a well regulated adjustable DC voltage or current source. NOTE: This manual contains information, instructions and diagrams which apply to a variety of standard constructions. If special features or modifications have been installed, the specific instructions peculiar to that modification

17、are contained in Addenda and take precedence where conflicts exist. Please take care to refer to the correct information for your unit. 1.2SAFETY PRECAUTIONS All EMS power supplies are designed to minimize the risk of fire or shock hazard operation. This instrument received comprehensive mechanical

18、and electrical inspection prior to shipment. Nevertheless, certain safety precautions must be observed. Only technically competent personnel familiar with the principles of electrical safety should operate this supply. To prevent fire or shock hazard, the power supply should not be exposed to water

19、or moisture. Electrical safety should be maintained at all times. Lethal voltages are developed within the power supplys enclosure. Therefore, the power supply must always be unplugged prior to removing the cover. If the input to the power supply is hardwired, the circuit breaker must be secured and

20、 the line fuses removed. Of course, dangers are inherent in high voltage equipment. However, a power supply with a low voltage output is also potentially dangerous considering the amount of energy (current) the supply is capable of delivering. In addition to the steady state energy available, power

21、supplies are typically terminated by very large capacitors, which can deliver huge surge currents capable of vaporizing metallic objects such as screwdrivers or jewelry. This could result in molten metal being sprayed. Proper care and judgment must always be observed. 1.Ensure all covers are in plac

22、e and securely fastened and the required ground is connected prior to supplying input AC power. 2.Proper grounding from the input AC power is required to reduce the risk of electric shock. Ensure that the ground connected has at least the same gauge wire as the supply leads. 3.Where high leakage exi

23、sts and there is a warning label on the rear panel, the protective earth ground must be connected. ( Symbol for protective earth ground). 4.Use extreme caution when connecting input AC power and never apply the incorrect input voltage, refer to ratings label. 83-473-000 Revision J 1 - 1 General Info

24、rmation 5.Use extreme caution when connecting the high voltage output cable including the separate ground connecting the supply to the load. 6.Ensure all load capacitors are completely discharged prior to connection. Never handle the output cable when the power supply is operating. 7.Always replace

25、fuses with the same type and Volt/Amp ratings. 8.Never attempt to operate the power supply in any manner not described in this manual. 9.Never remove DANGER and WARNING labels from the power supply, and replace lost or damaged labels immediately. 10. The power supply should only be serviced by Lambd

26、a EMI factory qualified personnel. 1.3SPECIFICATIONS All performance specifications, unless otherwise stated, are defined in the local programming configuration. Ripple, programming speed, transient response and stability are optimized with the power supply so configured. 1.3.1 INPUT POWER The follo

44、ATEGORIES ?Overvoltage Category II ?Pollution Degree 2 1.5.2 OPERATING TEMPERATURE All EMS power supplies are capable of continuous duty performance without deviation from their specifications in ambient temperatures between 0C and 50C. The output voltage temperature coefficient is 0.02%/C of the ra

45、ted output voltage. The output current temperature coefficient is 0.03%/C of the rated output current. For ambient temperatures between 50C and 70C the supplys output power is de-rated by a factor of 5% per 1C. Units may be safely stored at temperatures of -55C to +85C. 1.6OVER TEMPERATURE PROTECTIO

46、N Automatic protection against excessive temperatures is provided by a thermostat mounted on the heat sink. If the heat sink temperature reaches allowable maximum temperature, the unit will shut down to prevent damage. An automatic restart circuit will be activated once safe operating temperature le

47、vels are restored. 1.7OVERVOLTAGE PROTECTION (FOR OUTPUTS 300 VDC) The Overvoltage protection circuitry, adjustable from the front panel, is standard on all EMS models. This circuitry will short circuit (crowbar) the power supplys output to protect the load, and turns the control circuitry off if th

48、e output voltage reaches the preset value. This protection is effective regardless of the cause of the overvoltage. 1.8RSTL CONTROLLER BOARD This is an optional board that can be installed at the customers request. Units which have RSTL installed have all the features of a standard unit except Remot

49、e Sense. The installation of the RSTL would require an additional 1.75” to the height of the power supply. The board is designed for remote computer control, functionally duplicating the controls on the front panel of the power supply. These controls select the programming levels (Voltage and Current), and provide metering of the supplys output. The RSTL, when set in the REMOTE mode, disables the front panel controls (the meters still read), and asserts control of the power supply. RSTL is not currently available in CE m
