Established in 1971, Electronic Systems Industries (ELSIS) deals mainly with research and development, design and manufacturing of power electronic equipment.

The company’s products are made to industrial or military standards according to customer demands.

Power equipment for military applications

ELSIS’s main products are switch mode power supplies, battery chargers, DC/DC voltage converters, DC/AC inverters, uninterruptible power supplies, AC line voltage regulators, and electronic power management units.

ELSIS produces military-grade energy units, such as this charger, which is 220VAC - 50Hz input and 28VDC / 60A output.

The company’s 6kW AC/DC power supply unit offers 95% efficiency.

The 19in military-grade rack charger / power supply is specially designed for naval applications, featuring three x 115VAC - 60Hz input and 28VDC / 60A output.

The military DC/AC naval inverter is registered as 1,500VA. It is a 19in rack with pure sine-wave and 24VDC input and 220VAC / 50Hz output.

ELSIS’s DC/AC inverter is ideal for military purposes, with its 19in rack, pure sine-wave and 24VDC input, and 220VAC / 50Hz output.

A portable, intelligent lithium-ion battery charger has two x 16.8VDC batteries.

ELSIS offers a mil-spec smart lithium-ion and lithium-ion polymer batteries with Smbus v1.1 communication.

The majority of the units may be arranged for parallel-redundant operation.

Military-grade mobile and stationary chargers

ELSIS offers a military-grade charger unit that is 220VAC, with 50Hz input and 28VDC / 60A output.

These units are especially suitable for mobile and stationary use, and IP-20 protection class chargers. Additionally, they comply with stringent military specifications for choke, vibration, temperature, EMI / RFI, and electrical transients.

Efficient AC/DC power supply

ELSIS’s 6kW AC/DC power supply has a 95% efficiency rating. The unit features:

• 1U-19in ultra-compact housing
• Single or three-phase AC input
• RS422 and RS485 communication and control ports
• Up to 25 channels of controllable outputs
• Outputs can be adjusted from 25VDC to 48VDC

Naval-grade charger rack for energy supply

ELSIS supplies a 19in naval and military-grade rack that acts as both a charger and power supply. The rack is a three x 115VAC, with 60Hz input and 28VDC / 60A output.

The energy rack is specifically suited to naval use, with its 19in rack type and meeting IP-67 protection class. The unit has natural convection cooling, and complies with stringent naval military specifications for choke, vibration, temperature, salt mist, EMI / RFI and electrical transients.

Naval military-grade DC/AC inverter

The company also offers a 19in rack, pure sine-wave DC/AC naval inverter. It has specifications for 1,500VA, 24VDC input and 220VAC / 50Hz output.

The ELSIS inverter tool is specially designed for naval applications. It is a 19in rack type that meets protection class IP-67. The unit adheres to rigid naval military requirements for choke, vibration, temperature, salt mist, EMI / RFI and electrical transients. The ELSIS units are cooled by 24VDC waterproof fans against forced over-temperature operation.

Military-grade mobile and stationary DC/AC inverter

In contrast to the naval-specific unit, this 19in rack inverter, which also offers pure sine-wave and 24VDC input and 220VAC / 50Hz output, is made specifically for mobile and stationary use. It meets IP-20 protection class standards. It is made to comply with the choke, vibration, temperature, EMI / RFI and electrical transients of military class. The unit is cooled by internal fans and has a height of 2U.

Portable lithium ion battery charger

ELSIS supplies a portable, intelligent lithium ion battery charger that comes equipped with two 16.8VDC batteries. The multi-voltage input has a 12VDC – 32VDC, a 90VAC – 265VAC, and 50Hz. It complies with military specifications for choke, vibration, temperature, EMI / RFI and electrical transients.

High-spec smart and polymer lithium ion batteries

The company offers the military-spec smart lithium-ion and lithium-ion polymer batteries with Smbus V1.1 communication. The batteries feature:

• Maximum voltage of 33.0V, two sections each at 16.5V
• A capacity: In 30V mode, 3.75Ah / In 15V mode, 7Ah
• Storage temperature of -40°C to 70°C
• Temperature operations of -32°C to 60°C
• IP-67 protection class

BC2014 battery charger

• Up to four batteries can be charged simultaneously, including Li-Po batteries (for example, 2xBB2590, 4xBB2847 batteries can be charged in less than two hours)
• With suitable adaptors many variety of batteries can be charged
• ELSIS ‘BC2014’ chargers are in compliance with MIL-STD-1275E, MIL-STD-461E and MIL-STD-810E

E-switch and DCDC converter modules

• ‘I2C’ control and measurement facility
• Electronic circuit breaker, up to 50VDC to 40A
• DC / DC converter, 9VDC to 50VDC input and 3.3VDC to 48VDC / 0A to 10A output

2.5kW power supply

ELSIS’s new single phase, universal input, fan cooled, MIL-STD compliant ‘Battery Charger’ ELS-2K5-CHR provides 2.5kW of power with a leading efficiency of 95% at 26.7W/in³ outstanding power density. At 28VDC output ELS-2K5-CHR can supply up to 90Adc.

Three modules can be configured in either single or three phase in a standard 19in x 1U rack to provide 7.5kW output power.
