Options 

Our objective is to ensure that our customers have the best power conversion equipment available and that our power supplies have the flexibility suitable for your specific applications. We offer a wide variety of optional features and accessories that enhance the functional performance of Martek Power Abbott's standard power supplies.

Options available for specific models:

B and C OPTIONS - TERMINALS ON MOUNTING BASE
The electrical terminals extending through a glass sealed header may be located on mounting base (Option B) or a MilSpec Connector (described in Option A) may also be located on mounting base (Option C) on Abbott Series B, GB, S, U and V at a slight increase in price. This feature is not available on any model with a case size 1B.

E OPTION - SPECIAL ENCAPSULATION
All of our hermetically sealed power modules are encapsulated to meet or exceed the shock, acceleration, and vibration requirements of MIL-STD-810C. Special encapsulation to enable these modules to withstand higher shock levels of 60 g's, acceleration levels of 50 g's and vibration levels of 30 g's is available.

ER OPTION - ENHANCED RELIABILITY
The ER Option is available on standard power supplies to enhance their reliability. The ER option uses our standard proven circuitry coupled with a higher level of ER components, so that we guarantee the minimum predicted MTBF indicated in the table below. In addition, on a special order basis, we are able to customize the power supply by incorporating any level of ER components you designate in our field-proven circuits to comply with specific programs or application requirements.

SPECIAL TESTING
Customers may also enhance the predicted reliability of the power supply by designated special tests, e.g., Environmentla Stress Screening (ESS). These include special component prescreening or testing and special environment tests which include shock and vibration. We offer extended burn-in and temperature cycling as described below. Please consult your nearest Abbott sales office for complete details and prices.

TEMPERATURE CYCLING AND THERMAL SHOCK
Temperature cycling per MIL-STD-202E, method 102A and Thermal shock per MIL-STD-202E, method 107D are standard test parameters and procedures for this option. For other test parameters and procedures or MIL-STD test conditions, please consult your nearest sales office.

BURN-IN
Martek Power Abbott offers two types of burn-in to meet customer's requirements:

STATIC: Eachpower supply is subjected to continuous operation for a specific length of time at a maximum load and nominal input voltage. During testing, the power supply is mounted on a temperature stabilized aluminum plate. The temperature of the plate is maintained within 10°C of the maximum operating temperature of the power supply. The length of the burn-in may be specified by the customer.

DYNAMIC: Martek Power Abbott offers two types of dynamic burn-in:

  • The input voltage is electronically switched ON and OFF. The ON and OFF times can range from milliseconds to minutes.
  • The power supply is independently cycled between no load and full load.

F OPTION - EMI FILTER
This internal EMI filter provides attenuation to reduce conducted interference on input leads for Models BA and M. With this filter, the power supply will comply with MIL-STD-461A, Notice 3, CEO1 and CEO3 on the input leads. The addition of this filter alters the isolation of the input to case specification, 200 Vdc.

H OPTION MODIFIED INPUT for DC INPUT MODELS
DC INPUTS: This optionrecenters the input from the standard range 24 to 30 Vdc on Series B, BA, BC, C, CC, S and SN. The units can be modified to operate from any one of the other input voltage ranges shown below. Consult the factory if input voltage changes are desired on Model B17's.

H OPTION MODIFIED INPUT for AC INPUT MODELS
AC INPUTS: This option either recenters the input range to accommodate specific power line characteristics or widens the input range with, in some cases, derated output current. The various input combinationw for the models MH, MB, M, LV, LLV, WL, WWL and WM are shown below. This option is independent of Option -3.
