AdvancedTCA-compliant Power Modules Ease Telecom Equipment Design

From Tyco Electronics Power Systems, the PIM200 power input modules are designed to comply with the Advanced Telecom Computing Architecture (AdvancedTCA) specifications, providing telecom equipment manufacturers with a complete power solution for their AdvancedTCA boards. The PIM modules are rated for 200 W of maximum output power with a wide input voltage range of -38 Vdc to -75 Vdc, suitable for both -48 Vdc and -60 Vdc power distribution.

The PIM modules incorporate all of the power management features required by the AdvancedTCA PICMG 3.0 specification. Features include inrush current protection, O-Ring functionality with MOSFETs, EMI filtering to Class B CISPR limits and hot-plug capabilities. A variety of fault protection functions also are provided. These include A/B feed-loss alarm, 8 W of auxiliary power for IPMI and house keeping functions, and input undervoltage, overvoltage, overcurrent and thermal protections. In addition, the PIM200 modules provide a charging current at 72 Vdc for external holdup/energy storage bulk capacitors to reduce real estate on telecom boards. Sized at 2.78 in. × 1.45 in. × 0.5 in., the modules provide 97% efficiency at -48 Vdc.

As AdvancedTCA continues to gain traction within the telecommunications industry, we are proud to further advance the market with the first AdvancedTCA-compatible power input modules," said Sabi Varma, vice president, marketing and R&D, Tyco Electronics Power Systems.

The PIM200 modules are priced at $41.20 for 1000-unit quantities. Samples are available now.
