100W inverter

This inverter circuit will provide a very stable 230V Output Voltage. Frequency of operation is determined by a VR1 and is normally set to 60 Hz. Various “off the shelf” transformers can be used. Or Custom wind your own for best results. Additional MosFets can be paralleled for higher power. It is recommended to Have a “Fuse” in the Power Line and to always have a “Load connected”, while power is being applied. The Fuse should be10 Amps per 100 watts of output. The Power leads must be heavy enough wire to handle this High Current Draw

 
The pwm at IC1 CD4047 can be replaced with a 555 timer which is available in local stores.

1. Refer to the exhibit. A network administrator needs to add IP phones to the network. To which devices should the IP phones connect? AS1 and AS2 DS1 and DS2 DS1, DS2, and CS1 AS1, AS2, DS1, and DS2 2. Which CLI mode allows users to access all device commands, such as those used for configuration, management, and troubleshooting? user EXEC mode privileged EXEC mode global configuration mode interface configuration mode 3. Refer to the exhibit. Which Spanning Tree Protocol version is in effect? Per VLAN Spanning Tree (PVST) Per VLAN Spanning Tree + (PVST+) Common Spanning Tree (CST) Rapid Spanning Tree Protocol (RSTP) Multiple Spanning Tree Protocol (MSTP) 4. Refer to the exhibit. A network administrator has segmented the network into two VLANs and configured Router1 for inter-VLAN routing. A test of the network, however, shows that hosts on each VLAN can only access local resources and not resources on the other VLAN. What is the most likely cause of this pr

1. Refer to the exhibit. The Layer 2 switching design that is shown has been implemented in a campus environment that is using Spanning Tree Protocol. All inter-switch links that are shown are trunks. Whenever an inter-switch link fails, the network takes nearly a minute to completely converge. How can the convergence time be reduced? Increase the capacity of the distribution and core trunk links to 10 Gb/s. Add a trunk link that directly connects D1 and D2. Use Layer 3 switching on the core switch. Implement Rapid Spanning Tree Protocol 2. Refer to the exhibit. R1 is configured for traditional inter-VLAN routing. R1 can ping computer 3 but cannot ping computer 1. What is a possible cause for this failure? S1 port Fa0/11 is in the wrong VLAN. R1 does not have an active routing protocol. The IP address of computer 1 is in the wrong logical network. Router interface Fa0/0 has the wrong trunk encapsulation type configured. 3. Refer to the exhibit. What will allow a h

CCNA 2 Final Exam 2013 v 4   1. Refer to the exhibit. A network engineer removes a new router from the shipping container and powers on the router to ensure it passes POST. Which port would the engineer use to perform the initial configuration? AUX console FE0/0 FE0/1 2. What is the purpose of the TTL field within an IP packet header? clears an unreachable route from the routing table after the invalid timer expires prevents regular update messages from inappropriately reinstating a route that may have gone bad removes an unreachable route from the routing table after the flush timer expires limits the period of time or number of hops a packet can traverse through the network before it should be discarded used to mark the route as unreachable in a routing update that is sent to other routers 3. When would the network administrator use the ip bandwidth-percent eigrp as-number percent command? when there is a low bandwidth connection when the connec
