DescriptionElectronic Measurements MKA Series Power Supplies
SpecificationsINPUTSingle phase standard. For 3 phase consult factory. MK750 and MK1000 Units: 120 VAC (+10% -25%), 47-63 Hz standard. 240 VAC (+10% -25%), 47-63 Hz specify-240 Suffix 120 VAC-240 VAC Switch Option available on 750 and 1000 series, specify-120/240 Suffix. MK1500 Units: 240 VAC (+10% -25%), 47-63 Hz. For 120 VAC consult factory. Inrush Current: Automatic Inrush Current limiting (soft start).OUTPUT Voltage Adjustment: ±5% minimum. Regulation: Line: 0.2% for full line change. Load- 0 2% for 100% load change Ripple and Noise: 1% pk/pk or 50 rnV pk/pk (MK750 and MK1000 Units) or 75 mV pk/pk (MK1500 Units) whichever is greater (to 20 MHz). Transient Response: Output recovers to within 1% in less than 400 microseconds for a load change of 25% within the range of 25% to 100% load. Holdup Time: Output will remain within regulation limits for 20 milliseconds after loss of AC input power (from nominal line Voltage) at full load. Temperature Coefficient: ±0.02% per °C averaged over the Temperature range. Remote Sensing: Provided with open sense lead protection built in. Stability: ±0.1% maximum deviation for a 24-hour period, following an initial half-hour warm-up.EFFICIENCY Up to 85%.PROTECTION: Voltage: Over-voltage shutdown built into each model. OVP is factory set at 10 to 20% or 1-2 V. whichever is greater, above nominal output. This protection is reset by recycling the input power. Optional SCR crowbar can be provided for use along with standard OVP. Specify-CB Suffix. Current: Automatic Current limit/foldback. Thermal: Automatic shutdown when internal heat sink Temperature exceeds safe limit_ Automatic restarting when Temperature returns to normal. Reverse Voltage: Supply is inherently protected from reverse polarity Voltage across DC output terminals.CONVENIENCE FUNCTIONS Inhibit/Remote Shutdown: A short between two pins in auxiliary connection ii or a TTL zero can be used to turn the output of the power supply off. Margin Check: Pins are provided in the auxiliary connector for programming output ±5% for system margin check. Power Fail/Output Good Signal: TTL compatible signal goes to a logic zero when the AC input or DC output goes below minimum Operating level. (Standard on MK models, optional on MO models)OPERATING TEMPERATURE 00 to 71°C ambient. full output to 50°C. Derate 2% per °C to 71°C.STORAGE TEMPERATURE -400C to +850CCOOLING Integral ball bearing fan provides forced air cooling.ELECTRICAL TERMINATIONS Input: Barrier type — 6-32 hardware. Output: Studs — Two 5/16-18 UNC-2A: hex nuts provided. Output control connector (J1) 6 position — Molex No, 03-06-1061 mates with Molex No 03-06-2061.MECHANICAL & WEIGHT 14 — 16 LBS
