Model C2194A PTC PSU, Battery Charger 85-264ac; 12/24Vdc @ 0.66A

The PTC is a very compact combined Power Supply and Battery Charger system with integrated standby battery management ideally suited for RTU supply applications with Teleterm M2 Series Products. Just connect mains supply 85 to 264Vac , standby battery and load for an industrial grade standby power supply system for Remote Terminal Units.

This DIN rail mounted product is ideal for providing dc power to instrument systems where battery backup is necessary to ensure continuous system operation during power failure. Applications include RTU’s, dataloggers, remote field instruments, alarm systems and access controllers. Managing battery-backed systems for optimum backup time and battery life can be tricky and expensive. This product incorporates many features that make installing such systems simple and foolproof.

Batteries are capable of delivering enormous currents under system fault conditions that can damage wiring and equipment. The PTC incorporates an autoresettable load cutout, which disconnects the load under over-current fault condition. During prolonged power outages, the back-up battery will eventually discharge. If the load remains connected, the battery enters its deep discharge phase, which can cause irreparable damage to the battery, and reduce its capacity and life. The PTC incorporates an undervoltage cutout that disconnects the load when the battery voltage begins to fall.

This product is well proven in RTU and remote standby applications exposed to harsh environments.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
